An ideal gas confined in a cylinder

An Ideal Gas Confined in a Cylinder

Figure shows, an ideal monoatomic gas is confined in a horizontal cylinder by a spring loaded piston.

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 , pressure and volume and the spring is in its relaxed state. The gas is then heated very slowly to temperature , pressure and volume . During this process the piston moves out by a distance . Ignoring the friction between the piston and the cylinder, the correct statement (s) is (are):
