Air is contained in a piston-cylinder arrangement as shown in Fig. with a cross-sectional area of `4 cm^(2)` and an initial volume of `20 cc`. The air is initially at a pressure of 1 atm and temperature of `20^(@)C`. The piston is connected to a spring whose spring constant is `k = 10^(4) N//m`, and the spring is initially underformed. How much heat must be added to the air inside cylinder to increase the pressure to 3 atm (for air, `CV = 718 J//kg.^(@)C`, molecular of air 28.97)?
