Why is the temperature of a thermometer the same as the temperature of the surroundings?

∙ 6y ago
Heat energy gets exchanged between the thermometer and the surroundings. So, if you introduce the thermometer into a new surrounding, it will initially NOT have the same temperature. However, since it's small and doesn't have a lot of mass, it will soon lose or gain temperature, until it has the same temperature as its surroundings.

How long does it take for a thermometer to reach the same temp as its surroundings?
Generally, you must leave a thermometer in your mouth approximately three minutes to get an accurate reading.
What does it mean when a dry bulb thermometer reads the same temperature as a wet bulb thermometer?
100% RH
Is it normal for the temperature to go up on a thermometer when it has come out of a ice-water bath for 1 minute?
Assuming that the surroundings are above the freezing point of water - yes - it is normal for the temperature on the thermometer to go up. It may still remain elevated even if plunged back into the ice bath since the thermometer has mass and can absorb some energy while out of the bath. There is also the phenomena that in some thermometers even when the temperature drops, the thermometer fluid sometimes remains elevated unless you "shake down" the thermometer.
What would the temperature be inside of a C02 canister?
As long as the CO2 canister is not being emptied or filled, it will be at the same temperature as the room that it is in. If you actively emptying the canister, the temperature can go drop significantly because of the drop in pressure (see Ideal Gas Law), and it can get hot if you are filling it. In general, if an object is in thermal equilibrium with it's surroundings (true as long you are not changing its temperature or the temperature of the surroundings at a significant rate), the object will be the exact same temperature as the surroundings.
When thermometer is laid ouside the sun does it measure suns temperature or air temperature?
If a thermometer is laid out in direct sunlight, it will not measure the temperature of the air surrounding it. It will measure the temperature of the heat directly reaching it.

How a laboratory thermometer work?
It works when the thermometer gains heat from the surroundings. When the thermometer gains heat from the surroundings, gradually Mercury expands and it points the accurate measurement of temperature.
If thermometer is placed in sun light then which thing it will read the temperature of air or of sun or surrounding?
surroundings
What is the function of the laboratory thermometer?
A Thermometer is a Laboratory Equipment that measures temperature.
What is a probe thermometer?
this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
What is meant by the statement a thermometer measures its own temperature?
When a thermometer reaches thermal equilibrium, the temperature of the thermometer and the substance it is measuring are the same. Therefore, the thermometer is essentially measuring its own temperature.
How long does it take for a thermometer to reach the same temp as its surroundings?

What is a dual probe thermometer?
this is a thermometer that can work twice as much as a normal thermometer or a thermometer that can check the temperature of two things at the same time
How did the thermometer make life better?
yes, indeed thermometer makes life better. if there was no thermometer people would not know about the temperature varying in their body and if they had fever they would not be able to know and cure it. hen of course it would lead to deaths.therefore without thermometer there would have been thousands of deaths. there are different types of thermometer not only for body temperature but also for the surroundings.
What is the Reason for constriction in clinical thermometer?
Even after the removal of the thermometer right from the mouth of the patient the mercury which has been raised up will remain intact even though the temperature of the surroundings is less than the body temperature. So the physician can see the temperature without any hurry.
What does it mean when a dry bulb thermometer reads the same temperature as a wet bulb thermometer?
100% RH
What vertebrate groups have body temperatures the same as their surroundings?
The three Vertebrate groups that have the same temperature as their surroundings are Fish, Reptiles, and Amphibians. That means they are all cold blooded.
