20 kg steam at 100 kPa is contained in a spring-loaded piston-cylinder device with an initial volume of 2.00555 m3. Steam is now heated until its volume is qadrapled and its temperature is 600 C (a) Determine the work done and the heat transferred during the process. 4 points. (b) On a P-y diagram, sketch and label the temperature curve through each state and place the values of the specific 5. volume and pressure for each state on the -axis and P-axis, respectively. Make sure your temperature curves extend from the compressed liquid region into the superheat region. Also, place the value of the saturation pressure for each temperature curve on the P-axis. 2 points
