Heat Capacity - C - is a characteristic of a substance, the amount of heat required to change its temperature by one degree.
- Heat Capacity has units of energy per degree.
Heat capacity can be expressed like
Q = C dt (1)
where
Q = amount of heat supplied (J, Btu)
C = heat capacity of the system or object (J/K, Btu/lb oF)
dt = temperature rise (oK, oF)
The SI unit for heat capacity is J/K (joule per kelvin). In the English system, the units are British thermal units per pound per degree Fahrenheit (Btu/oF).
