This calculator determines the final volume of a gas given the initial temperature, initial volume, and final temperature. Enter these three values into the calculator below to determine the final volume.

## Charle’s Law Formula

The following formula describes the equation derived from Charle’s Law of ideal gases.

V₁ / T₁ = V₂ / T₂

- Where V1 is the initial volume
- V2 is the final volume
- T1 is the initial temperature
- T2 is the final temperature

Through this equation, we can re-arrange the variables to solve for the final volume of a gas going through a temperature and volume change. That equation is displayed as

(V₁ / T₁)*T₂ = V₂

It’s important to note, as with most laws involving gases, that these equations only work with ideal gases. Ideal gases behave in a way that lets scientist form clean equations for calculating their parameters.

## Charle’s Law Definition

Charles law describes that the temperature and volume of an ideal gas at any state are directly proportional .

## How to calculate final volume?
