A piston-cylinder device contains 50 kg of water at 250 kPa and 25°C. The cross-sectional area of the plunger is 0.1 m2. Heat is transferred to the water, causing some of it to evaporate and expand; When the volume reaches 0.2 m3, the piston hits a linear spring whose spring constant is 100 kN/m. More heat is transferred to the water until the plunger rises a further 20 cm. Determine a) the final pressure and temperature and b) the work done during this process. Also show the process on a P-V diagram. A piston-cylinder device contains 50 kg of water at 250 kPa and 25°C.The cross-sectional area of the plunger is 0.1 m2.
