Answer 2

The temperature and volume of a gas are directly proportional when pressure is constant.

Step-by-step explanation:

Charles's Law was proposed by a French chemist, Jacques Charles. The law states that "The volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".

The law shows the relationship between volume and temperature at a constant temperature. It is mathematically expressed as:

V∝T(P,n constant)
