Enter the heat capacity at constant pressure (J/K) and the heat capacity at constant volume (J/K) into the Calculator. The calculator will evaluate the Heat Capacity Ratio.

## Heat Capacity Ratio Formula

HCR = Cp / Cv

Variables:

• HCR is the Heat Capacity Ratio ()
• Cp is the heat capacity at constant pressure (J/K)
• Cv is the heat capacity at constant volume (J/K)

To calculate Heat Capacity Ratio, divide the heat capacity at constant pressure by the heat capacity at constant volume.

## How to Calculate Heat Capacity Ratio?

The following steps outline how to calculate the Heat Capacity Ratio.

1. First, determine the heat capacity at constant pressure (J/K).
2. Next, determine the heat capacity at constant volume (J/K).
3. Next, gather the formula from above = HCR = Cp / Cv.
4. Finally, calculate the Heat Capacity Ratio.
5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

heat capacity at constant pressure (J/K) = 50

heat capacity at constant volume (J/K) = 20
