## Charles’s law, law of volumes formula:

V1/T1 = V2/T2.

If the temperature increases, the volume of the gas also increases in proportion.

Definition of Charles’s law states:

Charles’s law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles’s law is:

When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related.

## How to do Charles law step by step examples:

Example 1:

5.00 L the volume of gas is at 300 K temperature. What is its volume at 200 K temperature?

Solution:

1) Charles law equation:

V1/T1 = V2/T2

2) equation values:

(300 K) / (5.00 L) = (200 K) / (x)

3) Multiply the left side and divide to solve for x.

x =( (200 K) * (5.00 L) ) / ( 300 K )

x = 3.33 L (two significant figures)

The temperature units of K will cancel. x is a symbol for an unknown and, technically, does not carry units. So do not write x L for x liters.

Example 2:

8.00 L the volume of gas is at 400 K temperature. What is its volume at 200 K temperature?

Solution:

1) Charles law equation:

V1/T1 = V2/T2

2) equation values:

(400 K) / (8.00 L) = (200 K) / (x)

3) Multiply the left side and divide to solve for x.

x =( (200 K) * (8.00 L) ) / ( 400 K )

x = 3.33 L (two significant figures)

The temperature units of K will cancel. x is a symbol for an unknown and, technically, does not carry units. So do not write x L for x liters.
