Enter the change in energy (J) and the change in pressure (Pa) into the Change in Volume Calculator. The calculator will evaluate and display the Change in Volume.

## Change in Volume Formula

The following formula is used to calculate the Change in Volume.

dV = dE / P
• Where dV is the Change in Volume (m^3)
• dE is the change in energy (J)
• P is the change in pressure (Pa)

To calculate a change in volume, divide the change in energy by the change in pressure.

## How to Calculate Change in Volume?

The following example problems outline how to calculate Change in Volume.

Example Problem #1:

1. First, determine the change in energy (J).
1. The change in energy (J) is given as: 500.
2. Next, determine the change in pressure (Pa).
1. The change in pressure (Pa) is provided as: 4.
3. Finally, calculate the Change in Volume using the equation above:

dV = dE / P

The values given above are inserted into the equation below:

dV = 500 / 4 = 125 (m^3)

Example Problem #2:

The variables needed for this problem are provided below:

change in energy (J) = 700

change in pressure (Pa) = 7

Entering these values and solving gives:

dV = dE / P = 100 (m^3)
