The temperature of water that is boiling may be determined with the use of laboratory thermometers. The temperature of water that is boiling may be determined with the use of laboratory thermometers.
Which thermometer can be used to gauge boiling water’s temperature?
As a result, the correct response is a laboratory thermometer.
Can the temperature be measured with a laboratory thermometer?
Since the average temperature of a human body is only 37 degrees Celsius, a laboratory thermometer cannot be used to accurately measure the temperature of a human body. The temperature range of a laboratory thermometer is often rather wide, ranging from –10 degrees Celsius to 110 degrees Celsius. In addition, laboratory thermometers do not contain a kink, which means that mercury falls on its own rather than being suspended.
How does a lab thermometer determine the temperature of water?
1 Answer
- Fill a beaker with water.
- Take a lab thermometer, hold it vertically, and submerge the bulb end in water. Make sure the entire bulb end is submerged.
- Keep an eye on how the mercury rises. Take the thermometer reading once it reaches a stable temperature.
- Take the reading after doing this again with hot water.
Can a thermometer be placed in boiling water?
The Method of Using Boiling Water
In a large saucepan, bring the water to a full and rapid boil. The stem of the thermometer should be submerged in the water that is boiling. Once more, ensure that it is submerged at a depth of at least two inches and wait for at least thirty seconds. Your thermometer should show 212 degrees Fahrenheit (or 100 degrees Celsius).
What does a boiling water measure in?
The temperature at which a liquid’s normal boiling point is reached is determined by the pressure at which the liquid is being heated; this is the point at which the pressure of the liquid’s vapor is equivalent to the pressure of the atmosphere at sea level (760 mm [29.92 inches] of mercury). Water begins to boil at 100 degrees Celsius (212 degrees Fahrenheit) at sea level.
Why can’t you use a thermometer from a lab?
since there is no sign of a kink in it. It does not contain the range that covers the temperature of the body. It is tough to manipulate in any way. Thermometers used in laboratories often do not have a digital display.
Can the temperature of boiling milk be measured with a medical thermometer?
No, since the range of a clinical thermometer is from 35 degrees Celsius to 42 degrees Celsius, yet the temperature at which liquids boil is far higher than 42 degrees Celsius.
Why isn’t the temperature of boiling milk measured with a clinical thermometer?
Because the temperature of boiling water will rise above this limit, a clinical thermometer cannot be used to measure the temperature of boiling milk. Because the range of a clinical thermometer only varies between 35 degrees Celsius and 42 degrees Celsius, we are unable to use a clinical thermometer to measure the temperature of boiling milk.
Can a standard thermometer be used to gauge the temperature of water?
Digital medical thermometers are primarily designed to monitor the temperature of the human body, hence their measuring range is quite limited. The temperature of water may range from scalding to subzero. Its range is fairly extensive. A standard thermometer will not be able to take accurate readings in this temperature range.
Why is it possible to gauge the temperature of boiling water using a clinical thermometer?
Solution. A clinical thermometer cannot be used, contrary to popular belief, to measure the temperature of water that is already boiling. It just covers a very limited area. It is possible for it to crack when it is either too hot or too cold.
Is it possible to use a meat thermometer for liquids?
The temperature of some liquids may be measured using a meat thermometer; however, if the liquid’s boiling point is higher than 220 degrees Fahrenheit, the meat thermometer will not be able to accurately determine the temperature of the liquid.
What will happen if boiling water is poured over a clinical thermometer?
The thermal expansion of the mercury contained in the thermometer’s capillary tube will cause the thermometer’s capilary to break if it is used to sterilize a clinical thermometer with boiling water.
Which set of lab tools can be used to determine a liquid’s boiling point?
The Thiele tube technique is one of the easiest ways to determine the boiling point of a compound. This approach also has the benefit of just requiring a tiny quantity of the substance to be tested (less than 0.5mL of sample). A capillary tube is turned upside down and inserted inside of a smaller tube before the sample is added.
What distinguishes a clinical thermometer from a laboratory thermometer?
A clinical thermometer is the instrument that is used to measure the temperature of a human body. The temperature of the body is not measured using a laboratory thermometer; rather, this type of thermometer is used for the measurement of items that typically have a temperature range that is different from that of a typical human body.
Can a body temperature greater than 200 degrees be measured with a laboratory thermometer?
The temperature of a human body cannot be accurately measured using a thermometer designed for use in a laboratory. This is due to the fact that as soon as the bulb of the scientific thermometer is removed from our lips, the amount of mercury that is contained within its tube will begin to rapidly decrease. This will produce an inaccurate reading of the temperature of the body.
What is a thermometer’s king?
The kink in the capillary tube of the mercury thermometer serves to prevent mercury from falling into the bulb of the thermometer. The user will always get an accurate reading of the temperature thanks to this feature.
Which thermometer is employed to determine the liquid’s temperature?
The temperature scales for Celsius and Fahrenheit are often shown on either side of the tube on liquid thermometers. This allows the thermometer to read temperatures in either system. One common kind of thermometer used with liquids is called a maximum thermometer. When the temperature rises, the liquid in the maximum thermometer is forced above the glass tube, but it is unable to do so easily when the temperature drops.
What temperatures can’t be measured by a clinical thermometer?
A clinical or laboratory thermometer will not accurately read the temperature of water that is already boiling.
Can we use a clinical thermometer to measure the temperature of any other object? If so, explain how and draw a diagram.
There is no clinical thermometer that just measures body temperature, hence the answer is no.
What does a seventh-grade laboratory thermometer do?
Thermometers used in laboratories and classrooms are referred to as laboratory or lab thermometers. These are the instruments that are used to monitor temperatures for scientific study. The temperatures of substances, as well as their points of boiling and freezing, may be measured with thermometers manufactured specifically for use in laboratories.
Can the temperature of ice be measured with a medical thermometer?
Thermometers designed for clinical usage can also be utilized for measuring the temperature of ice water.
How do you determine the water’s temperature?
Put your elbow in the water and look around.
Put one of your elbows into the water if the container of water is deep enough. This will provide you with an approximation of the temperature of the water. You will have the ability to immediately determine if the water is warm or cool. Avoid placing your hand into water whose temperature you are unsure of because you run the risk of scalding yourself.
Can I cook with a medical thermometer?
The thermometers that are used to measure the temperature of the human body do not read temperatures that are high enough to be utilized in cooking. They are not constructed to endure temperatures higher than 106 degrees Fahrenheit (41.1 degrees Celsius). Because of this, a medical thermometer should never be used in the kitchen.
Can you check the temperature of water with a candy thermometer?
Put the candy thermometer into a saucepan of water, then raise the water to a full boil. It is important that the bubbles remain consistent and active. This will serve as our starting point; the temperature at which water boils at sea level is 212 degrees Fahrenheit, or 100 degrees Celsius. If you want an accurate reading from your thermometer, you should let it sit in the water for five minutes before taking it out.
Can hot oil be measured with a meat thermometer?
However, a large number of digital thermometers with rapid readouts are designed to be used in a wide range of cooking temperatures, including extremely high heat, such as that produced by hot frying oil. Therefore, it is possible to utilize them during deep frying in order to maintain the appropriate temperatures for cooking.
Any thermometer will work for oil, right?
Even while having a kitchen thermometer makes things much simpler, it is not impossible to achieve the desired temperature without using one. If you have a thermometer, all you need to do to determine the temperature of the oil is check it. The temperature range of 350–365 degrees Fahrenheit is the sweet spot for the majority of frying applications. If the temperature reads that on your thermometer, you are good to go.
Can soup be tested with a meat thermometer?
Choosing the Right Thermometer for Your Food
Insert the needle at a depth of two to two and a half inches into the area of the meal that is the thickest. The readings of the temperature will be provided in one to two minutes. Roasts, casseroles, and soups all benefit from being measured with this sort of thermometer. They are not suitable for foods that are thin.
Can boiling points be determined using thermometers?
In order to accurately determine the temperature at which water boils, a thermometer must be able to measure temperatures at least as high as the target temperature. Thermometers used in laboratories are purpose-built instruments that are able to accurately measure extremely high temperatures as well as the points at which liquids boil. They have a great degree of accuracy for measuring degrees of boiling.
What measuring device is used to determine boiling point?
A manometer 6 is used to determine the pressure that is being exerted on the outside of the U-tube 2. The liquid is allowed to boil briskly until all of the air on the sample side of the U-tube 2 has been eliminated.
What tool is used to determine a solution’s boiling point?
An ebullioscope, whose name derives from the Latin verb bullere, which means “to boil,” and the suffix -scope, is a device that determines the temperature at which a liquid boils. The elevation of the boiling point may be used to either determine the alcoholic strength of a combination or the molecular weight of a non-volatile solute. Both of these calculations are based on the elevation of the boiling point.
How much longer is a laboratory thermometer than a clinical thermometer?
On the other hand, a thermometer used in the laboratory can detect temperatures ranging from -10 degrees Celsius to 110 degrees Celsius. Therefore, in order to measure such a wide temperature range, the tube needs to be as long as it possibly can be, which results in the laboratory thermometer having a long form factor.
Which thermometer—clinical or laboratory—is more accurate?
The temperature range that can be measured by a clinical thermometer is between 35 and 42 degrees Celsius, but the temperature range that can be measured by a laboratory thermometer is between -10 and 110 degrees Celsius.
How can we use a thermometer in a lab or a medical setting?
In order to obtain an accurate reading of the patient’s internal temperature, the thermometer must first be inserted into the patient’s mouth. The temperature of the mercury in the glass bulb rises as a result of the heat generated by the body. This causes the mercury to expand, and once it reaches a particular point, it begins to flow through the thin capillary thread.
If so, how can you measure heat with a thermometer? If not, why not?
Explanation: This is true, but only for heat that can be felt! In point of fact, the range of temperatures that a heat thermometer is able to monitor is merely the human body. Nevertheless, there are thermometers that can measure temperatures higher than that.
Has mercury been used in laboratory thermometers?
Mercury thermometers are versatile instruments that may measure the temperature of a body, a liquid, or a vapor. Thermometers that contain mercury are frequently seen in domestic and commercial settings, in addition to laboratories and manufacturing facilities.
Why does a thermometer use mercury?
Mercury is the only element that can be found in its liquid state at ambient temperature. As a result of its high coefficient of expansion, it is frequently found in thermometers. When it is employed in a thermometer, even the smallest change in temperature may be detected and shown accurately. In addition, it has a high boiling point, which makes it particularly well-suited for use in determining temperatures of a higher range.
As opposed to alcohol thermometers, why do we use mercury thermometers?
The coefficient of thermal expansion of mercury is significantly higher than that of alcohol. This indicates that a column of mercury will expand and rise more than a column of alcohol when subjected to the same change in temperature. Because of this, measurements obtained with mercury can be more precise.
Which thermometer is employed when water is boiling?
As a result, the correct response is a laboratory thermometer.
The ideal thermometer to use when measuring boiling water
The reading of an instant-read thermometer of good quality, such as the ThermoWorks Thermapen ONE, should be within +/-0.5 degrees Fahrenheit of the boiling point for your area. A good grade bimetal thermometer, such as the Tel-Tru BQ300 BBQ Thermometer, should give a reading that is within +/- 2 degrees Fahrenheit of the boiling point.
What can’t be used to measure boiling water’s temperature?
A clinical thermometer will not accurately register the temperature of water that is boiling. The reason for this is because the temperature range that a clinical thermometer can measure is limited between 35 and 42 degrees Celsius.
What is the purpose of a laboratory thermometer?
A laboratory thermometer, often referred to more informally as a lab thermometer, is a type of thermometer that is used to measure temperatures other than the temperature of the human body. The temperature may be anything from -10 C to 110 C. Thermometers created specifically for use in laboratories are called laboratory thermometers. These thermometers may be used to determine the boiling point, the freezing point, or the temperature of other substances.
Which of the following statements regarding laboratory thermometers is false?
The thermometers used in laboratories are not accurate enough to measure the temperature of the human body.
Who made the thermometer?
Santorio Santorio (1561-1636) of Italy is commonly credited with having affixed a scale to an air thermoscope at least as early as 1612, and as a result, he is regarded to be the inventor of the thermometer as a temperature measurement instrument. Santorio Santorio was born in 1561 and died in 1636.
What is Ncert for laboratory thermometers?
