To find out what factor increased the volume, we should use the ideal gas law:

PV = nRT.

As the temperature, gas constant, and the amount of substance of gas are constant, then we have the equation:

n1RT1 = n2RT2;

So, the pressure increased the volume and this is shown in next equation:

P1V1 = P2V2;

7.2P₁ = 54P_2;

P₁/P₂ = 54/7.2;

P₁/P₂ = 7.5.
