As the liquid in the thermometer is heated it expands, and the only way the expanding liquid can go is upward. As the liquid in the thermometer cools, it will contract, and the liquid will fall back down into the resevoir, causing the column of liquid to move downward.
A glass bulb of a thermometer is the part at the bottom of the thermometer that contains mercury or colored alcohol that expands and contracts with temperature changes. This expansion and contraction of the liquid is what causes the thermometer to measure and display the temperature.
A liquid-in-glass thermometer is a type of thermometer that consists of a glass tube filled with a liquid, typically mercury or alcohol, which expands or contracts with changes in temperature. The level of the liquid in the tube corresponds to the temperature, allowing for temperature measurement.
A liquid-in-glass thermometer works based on the principle of thermal expansion. As temperature increases, the liquid inside the thermometer expands and rises in the calibrated glass tube. The level of the liquid indicates the temperature which corresponds with a specific scale on the thermometer.
The glass on the bulb of a clinical thermometer is thin to allow for rapid heat transfer between the body and the thermometer. This ensures that the thermometer can quickly and accurately measure the body's temperature. Additionally, thin glass reduces the risk of the thermometer causing discomfort when inserted into the mouth or underarm.
You can clean a glass thermometer by washing it with warm, soapy water and rinsing it thoroughly. Ensure that the thermometer is completely dry before storing it. Avoid using harsh chemicals or abrasive materials to clean the thermometer.

Temperature affects the amount the mercury is spread out. Heat causes most liquids to expand, which is how a thermometer works. As heat around the glass protecting the mercury of the thermometer rises, the mercury expands and covers more room in the thermometer.

mercury
The sensor in a mercury-in-glass thermometer is the glass bulb at the base of the thermometer containing the mercury. The temperature is measured by the expansion or contraction of the mercury based on the surrounding temperature, allowing the thermometer to provide a temperature reading.
