Molar heat capacity
When using SI units, it can be calculated with the equation
The molar heat capacity of a given substance can be found by heating the substance by releasing a known amount of energy into the substance and measuring the temperature change.
For example, a common school experiment to find the molar heat capacity of water involves heating a beaker of water with an immersion heater (that can display the heat released in joules on a display) and stirring the water, while checking the temperature at specific intervals.
For more accurate results, a bomb calorimeter can be used; these contain a chamber of fuel (in this case, a compound that will release heat when needed) inside a chamber of water, with the water chamber protected by heat-proof walls (to ensure minimal heat loss, which would affect the final heat capacity recorded).
