The cylinder in the figure has a movable piston attached to a spring. The pressure in the surroundings is

. The cylinder 's cross-section area is

, it contains

of gas, and the spring constant is

. At

the spring is neither compressed nor stretched. Then the gas is heated up and the spring is accordingly compressed by

when reaching a new equilibrium. (a) What is the volume of gas in the new equilibrium state? (b) What is the pressure of gas in the new equilibrium state? (c) What is the temperature of gas in the new equilibrium state?
