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) 

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)
