Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

$PV = K$
