Problem 1: a) Water at 1 bar, 20 °C is heated at const P to produce steam with quality 95%. What is the amount of heat?

b) Steam at 1 bar 400 °C is cooled by removing 300 kJ/kg of heat at constant pressure. What is the final temperature? If the state is a vapor-liquid mixture, report the mass fraction in each phase.

Problem 2: Water at 20 °C 30 bar is heated in a closed system under constant pressure.

a) If the quality in the final state is 75%, what is the amount of heat?

b) If the amount of heat is 2000 kJ/kg, what is the final temperature?

c) If the amount of heat is 3000 kJ/kg, what is the final temperature?
