Heat Capacity
Captions available
The idea
Heat capacity is the heat a body absorbs or releases per degree of change, scaling with the matter present.
In practice
A swimming pool holds a far greater heat capacity than a cup of water, since it contains vastly more matter to heat.
Where people slip
Heat capacity is extensive — comparing capacities compares amounts of substance, never what each is made of.
