11. A piston-cylinder assembly shown below is initially containing 2g of air at STP. Heat is then added until the temperature of the air inside the system reaches 250°C and pressure of 3kPag. Determine the work done (k) by fluid due to expansion. Calculate also the required spring constant (N/mm) necessary to compensate the expansion of the cylinder. SPRING Air at STP D- 30cm Heat
