Does a thermometer measure heat or temperature explain?
Despite its name, however, a thermometer does not actually record heat, but rather temperature. Temperature is a measure of the average kinetic energy of the molecules within a substance.
What is thermometer chemistry?
Thermometers are devices for measuring temperature. In a thermometer with liquid, mercury or alcohol is placed in a small glass container. If temperature increases, the liquid undergoes volume expansion and rises in a capillary. The level of the raised liquid is the measure of temperature.
What is the function of a thermometer?
A thermometer is an instrument that measures temperature. It can measure the temperature of a solid such as food, a liquid such as water, or a gas such as air. The three most common units of measurement for temperature are Celsius, Fahrenheit, and kelvin.
