Detailed Solution

The given statement is true.
Concept- The foundation of laboratory thermometers is mercury-based thermometers. The glass housing of a thermometer houses a narrow mercury column. The mercury inside the tube expands as the temperature rises. Since the tube's surface area is fixed, the expansion results in a rise in the mercury column's height, which is translated into an increase in temperature.
A glass capillary tube with a fine bore and a thick wall makes up a laboratory thermometer. It is filled with pure, dry, or coloured alcohol and has a tiny, thin bulb at its lower end. The term "stem" refers to the area of the capillary tube that is located above the bulb. The Celsius scale used to make laboratory thermometers ranges from

.
The design of laboratory thermometers is based on mercury-based thermometers. Typically, the bulb's wall is thin. The capillary tube is quite small. This contributes to the thermometer becoming more sensitive.

The glass wall of the thermometer reaches thermal equilibrium with our body when it is employed to measure our body temperature. At some point, the mercury that is in touch with the glass wall will achieve thermal equilibrium. We can state that our body and mercury are in thermal equilibrium, or at the same temperature, using the zeroth law of thermodynamics. The mercury thermometer measures the temperature in this manner.
Although a thermometer must make physical touch with the system to determine temperature, heat can also flow without physical contact. There are several ways to transfer heat, including conduction, convection, and radiation. Mercury thermometers change size as a result of changes in temperature.
