Choose C. Explanation: The ideal gas state equation is PV=nRT, where P is the pressure of the ideal gas, V is its volume, n is the amount of substance of the ideal gas, R is the gas constant, and T is the temperature. When an ideal gas is in state 1: P1V1 = n1RT1, and in state 2: P2V2 = n2RT2. The amount of gas remains constant, that is, n1 = n2. By dividing these two equations, we get: P1V1/T1 = P2V2/T2
