## 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)

## How to Calculate Change in Volume?

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

Example Problem #1:

- First, determine the change in energy (J).
- The change in energy (J) is given as: 500.

- Next, determine the change in pressure (Pa).
- The change in pressure (Pa) is provided as: 4.

- 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)
