Heat is a form of energy that gives the sensation of hotness or coldness of a body, whereas the temperature tells how hot or cold a body is.
The flow of energy from a warm to a cooler object is known as heat. The transfer of heat energy is from a higher-temperature material to a lower-temperature substance. It is due to the fact that faster-vibrating molecules shift their energy to slower-vibrating molecules. The body’s heat content determines whether it is hot or cold. The body will get hotter as the heat content increases.
Temperature is a measure of the average kinetic energy of the particles in an object. When temperature increases, the motion of these particles also increases. A thermometer or a calorimeter is used to determine the temperature. In other terms, the internal energy of a system is determined by its temperature.
