561 dm 3 of a gas at S.T.P. is filled in a 748 dm 3 container. If temperature is constant, calculate the percentage change in pressure required.

V 1 = 561 dm 3 P 1 = P V 2 = 748 dm 3 P 2 = ? By Boyle's Law: Substituting the values : Change in pressure = P - 0.75P = 0.25P decrease Percentage decrease in pressure = x 100 = x 100 = 25% ∴ Percentage decrease in the pressure of the gas = 25%
