2: A piston-cylinder assembly contains air at 210 kPa and occupies a volume of 0.01m'. The piston is attached to one end of a spring and the other end of the spring is fixed to a wall. The force exerted by the spring on the piston is proportional to the decrease in the length of the spring. The ambient atmospheric pressure is 100 kPa. Now, the air in the cylinder is heated till the volume is doubled and at this instant it is found that the pressure of the air in the cylinder is 600 kPa. Sketch the process on p-v diagram and calculate work done by the gas.
