Charles' Law Calculator

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

Initial volume

Initial temperature (K)

Final temperature (K)

Final volume 1.167

Formula: V₁/T₁ = V₂/T₂

Step-by-step with your numbers:

1. Values used:

2. Initial volume = 1

3. Initial temperature = 300 K

4. Final temperature = 350 K

6. Final volume = 1.167

Did we solve your problem today?

Charles's law: at constant pressure, gas volume is proportional to absolute temperature.

The math behind it

V₁/T₁ = V₂/T₂, with temperatures in kelvin.

1 L at 300 K heated to 350 K → about 1.17 L.

Why kelvin?

Gas laws need an absolute temperature scale starting at absolute zero.
