QUESTION

5

[11]

A piston cylinder device is filled with water at

100 -

kPa. At this point the piston rests on a set of stops. Heat is now added to the device until the water reaches a pressure of

250 -

kPa and the water has completely vaporized. At this point the the piston starts to lift from the stops. Heat is further added until the temperature of the water reaches

250 C .

Draw the process on

T - v

and

P - v

diagrams and calculate the change in internal energy for the entire process.
