Question

One mole of an ideal gas (Cp = 2.5R) is contained in a piston-cylinder arrangement at 2 bar
and 300 K with a spring attached to the wall and piston as shown in the figure below. Initially,
the spring is stretched up to 1 cm. The gas is heated so that the piston moves by 3 cm and the
final temperature becomes 310 K. The diameter of piston is 10 cm. Find the heat added to
the gas. The surrounding pressure is 1 atm.
