Liquid-in-glass thermometers work by using the expansion and contraction of a liquid, like mercury or alcohol, inside a glass tube. The liquid’s level rises or falls as temperature changes.
Liquid-in-glass thermometers operate based on the principle that liquids expand and contract with temperature changes. A liquid, such as mercury or alcohol, is sealed inside a thin glass tube. When the temperature increases, the liquid expands and rises in the tube. Conversely, when the temperature decreases, the liquid contracts and falls. The level of the liquid corresponds to a temperature scale marked on the thermometer, providing an accurate reading.

Liquid-in-glass thermometers function by exploiting the thermal expansion properties of liquids like mercury or alcohol. These liquids are enclosed within a narrow glass tube. As the surrounding temperature increases, the liquid absorbs heat, causing it to expand and rise in the tube. When the temperature decreases, the liquid cools, contracts, and descends. The liquid’s height correlates with a calibrated scale marked on the glass, allowing the thermometer to provide a precise temperature reading based on the liquid’s position.
