If it's an Ideal Gas then it's : PV=nRT or V=(nRT)/P

Explanation:

For Ideal Gas : PV=nRT or V=(nRT)/P
P : Pressure (Pa)
V : Volume (m^3)
n : amount of substance of the gas (mol)
R : gas constante (8.314 J.K^-1.mol^-1)
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

V prop T

or V=kT,

where V is the volume of the sample of gas, T its temperature in Kelvin and k is constant of proportionality.

Alternatively it can be written as
V_1/T_1=V_2/T_2
