Heat may be defined as energy in transit from a high temperature object to a lower temperature object. An object does not possess heat; 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.
