In a piston-cylinder assembly, there is initially 2 kg of water at a temperature of 25 °C and a pressure of 100 kPa. Then heat is given to the water until its volume is 0.4 m3. At this point, the piston in the cylinder is fixed with a stopper, but the water in the cylinder continues to heat until its temperature reaches 300 oC. According to this, calculate a) the final pressure of the water, b) the amount of heat given to the water, c) the work done by the piston. d) Show these processes in the T-v (Temperature-Specific Volume) diagram
