Laboratory Thermometer

The temperature of a body is basically a measurement of the degree of hotness or coldness. The molecules of a gas or liquid or solid are in constant motion. This motion of molecules constitutes the kinetic energy of each molecule. As a matter of fact, the temperature is nothing but the average kinetic energy of all the molecules present in the body. Greater is the kinetic energy, higher is the temperature. In addition, the temperature is one of the seven standard physical quantities which cannot be derived from any other quantity.
