If measurements of a gas are 75l and 300 kilopascals and then the gas is measured a second Time and found to be 50L describe what had to happen to the pressure

In this problem, the ideal gas equation PV=nRT is applied. In this relationship, volume is inversely proportional to pressure. Hence, pressure increases when volume decreases, vice versa. In this case, volume is decreased from 75 to 50 L, so the pressure is expected to increase above 300 kilopascals.
