Heat capacity, also called specific heat capacity is the amount of heat it takes to make a certain mass of a substance increase by a certain amount of temperature. The unit of calorie is defined by the heat capacity of water: 1 calorie is defined as the amound of heat it takes to heat 1 gram of water 1 degree Celsius.
A table of heat capacities of select substances is as follows:
| Substance | Heat Capacity |
|---|---|
| Copper | 0.092 |
| Glass | 0.200 |
| Iron | 0.108 |
| Styrofoam | 11.95 |
| Water | 1.00 |
