Q1. A piston/cylinder assembly contains 1 mole of air at 20C and 100 kPa, as shown in the figure below. There is a linear, elastic spring mounted on the piston such that when the air is heated, the pressure reaches 111 kPa with a volume of 0.03 m?. a) Find the final temperature. b) Plot the process in a P-V diagram. c) Find the work done to push the spring.
