Traditional bulb thermometers rely on the expansion and contraction of liquids (like alcohol or historically mercury) as temperatures fluctuate. As the temperature increases, the liquid expands and moves up the narrow, calibrated glass tube.

The thermometer is a fundamental tool that has allowed humanity to quantify heat, from measuring the warmth of a child to monitoring industrial processes. Simply defined, a thermometer is an instrument designed to measure the temperature of solids, liquids, or gases, or to determine the temperature gradient between two points. It works by identifying a change in the physical properties of a sensor, such as liquid expansion or electrical resistance, and converting that change into a numerical value.
