Heat may be defined as energy in transit from a high temperature object to a lower temperature object. An object does not possess &quot;heat&quot;; the appropriate term for the microscopic energy in an object is internal energy. The internal energy may be increased by transferring energy to the object from a higher temperature (hotter) object - this is properly called heating.

The measurement of heat flow is called calorimetry. Heat, as distinct from temperature, can only be measured using a medium, i.e. a substance of known specific heat. Then by measuring its temperature the amount of heat can be calculated. Water is the easiest to use, at least up to its boiling point, and by definition, a rise of 1 deg C per gram of water is 1 calorie. One of the most frequent needs to measure heat is in power stations or industrial processes which use water or steam. If you are working out heat flow using steam you have to use steam tables which are calculated giving the heat content per unit mass of steam at various pressures and temperatures. Sometimes you would need to measure heat flows in other fluids, such as at an oil refinery, then you would have to know the specific heat (that is the heat per degree of temperature) of the fluid being handled.
