Question

When we take out a laboratory thermometer from boiling water, the mercury level does not fall even after few minutes.

• A. True
• B. False

Answer 1

The correct option is B False

When we take out the laboratory thermometer from boiling water, the mercury level fall down after few minutes due to fall in temperature. This is due to the absence of constriction in case of laboratory thermometer. Thus, reading from a laboratory thermometer should be taken while it is still in touch with the body whose temperature is to be measured.
