Learn More### How to Calculate Heat Capacity: 8 Steps (with Pictures

2019-4-25 · To calculate heat capacity, use the formula: heat capacity = E / T, where E is the amount of heat energy supplied and T is the change in temperature. For example, if it takes 2,000 Joules of energy to heat up a block 5 degrees Celsius, the formula would look like: heat capacity = 2,000 Joules / 5 C.
