Charles law calculator is used to find the initial & final volume and the initial & final temperature of an ideal gas. This tool calculates the missing values of the formula of the Charles law.

## What is Charles's law?

Charles law is a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature if the pressure remains constant.

## Formula of Charles law

## How to calculate the volume of gas using Charles's law?

Below is a solved example of Charles's law.

**Example**

Find the final volume (V_{2}) of the gas by using Charles law, if V_{1} = 12L, T_{1} = 4K, & T_{2} = 8k.

**Solution**

**Step 1: **Identify the given terms of volume and temperature.

Initial temperature = T_{1} = 4k

Final temperature = T_{2} = 8k

Initial volume = V_{1} = 12L

Final volume = V_{2} =?

**Step 2: **Substitute the given terms in the formula of Charles's law.

V_{1}/T_{1} = V_{2}/T_{2}

12L/4K = V_{2}/8k

(12L/4K) * 8k = V_{2}

3L * 8 = V_{2}

24L = V_{2}

Hence the final volume of the gas is 24L.
