Problem 1: Wet steam with quality 63.1% exchanges heat in a closed system under constant pressure P = 6 bar. Determine the final temperature and the amount of PV work in each of the following cases:

a) The system is cooled by removing 1500 kJ/kg of heat.

b) The system is heated by adding 1500 kJ/kg of heat. Report the work using the proper sign convention.

Problem 2: a) 200 kJ of heat is added under constant pressure to 1 kg of steam initially at 30 bar, 400 °C. What is the final temperature?

b) What is the change in internal energy during this process?
