Boyle's Law Calculator

Find the new pressure of a gas when its volume changes at constant temperature.

Initial pressure (kPa)

Initial volume

Final volume

Calculated Output

Final pressure (kPa) 200

Formula: P₁V₁ = P₂V₂

Step-by-Step Breakdown

1. Values used:

2. Initial pressure = 100 kPa

3. Initial volume = 2

4. Final volume = 1

6. Final pressure = Initial pressure x Initial volume = 100 x 2 = 200kPa

Did this calculator solve your problem today?

The math behind it

P₁V₁ = P₂V₂. Halving the volume doubles the pressure.

100 kPa at 2 L compressed to 1 L → 200 kPa.

What must stay constant?

Temperature and the amount of gas.
