An ideal gas occupies 400 L at an absolute pressure of 500 kPa. Find the absolute pressure if the volume changes to 950 L and the temperature remains constant.

According to Boyle's Law, for a given mass of gas at constant temperature, the product of pressure and volume is constant (P1V1 = P2V2). Here, P1 = 500 kPa, V1 = 400 L, V2 = 950 L. Solving for P2 gives P2 = (P1V1)/V2 = (500 kPa * 400 L) / 950 L = 210.53 kPa, which rounds to 210 kPa.
