Specific heat capacity
The specific heat capacity (symbol c or s, also called specific heat) of a substance is defined as heat capacity per unit mass. The SI unit for specific heat capacity is the joule per kilogram kelvin, the amount of heat energy (measured in joules) required to raise the temperature of one kilogram of the substance by one kelvin. Heat capacity can be measured by using calorimetry.

Factors that influence heat capacity measurements
- Temperature: For example, measuring the heat capacity of water produces different results if the starting point is 20 °C rather than 60 °C.
- Intermolecular forces: If a fluid has strong intermolecular forces (such as hydrogen bonding in water) then the heat capacity is likely to be higher.
