An ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston (as shown in the figure). Initially the gas is at temperature T, pressure P and volume V, and the spring is in its relaxed state. The gas is then heated very slowly to temperature T2, pressure P and volume V. During this process the piston moves out by a distance x. Ignoring the friction between the piston and the cylinder, the correct statement(s) is(are) (A) If V = 2V and T = 3T, then the energy stored in the spring is P.V. (B) If V = 2V and T = 3T, then the change in internal energy is 3P, V (C) If V = 3V and T = 4T, then the work done by the gas is P,V 3 (D) If V = 3V and T = 4T, then the heat supplied to the gas is PV, 000000
