What Is Heat Capacity? Sciencing

Heat capacity is a term in physics that describes how much heat must be added to a substance to raise its temperature by 1 degree Celsius. This is related to, but distinct from, specific heat, which is the amount of heat needed to raise exactly 1 gram (or some other fixed unit of mass) of a substance by 1 degree Celsius. ...
