# Which gas law states that the volume of a gas is directly proportional to its temperature?

##### 2 Answers

If it's an Ideal Gas then it's :

#### Explanation:

For Ideal Gas :

**P : Pressure #(Pa)#**

**V : Volume**#(m^3)#

**n : amount of substance of the gas**#(mol)#

**R : gas constante**

**T : absolute temperature**#(K)#

(SI base unit)

I have a different answer.

Charles's law, an experimental gas law, describes how gases tend to expand on heating.

#### Explanation:

Charles's law, which is also know as Law of Volumes, states that

For a sample of a dry gas, its volume and Kelvin temperature are directly related, provided pressure is held constant.

Mathematically relationship can be written as
