1. Water at 100 kPa, 25?C is brought to the boiling point in a piston/cylinder with an isobaric process. The heat is supplied by a heat pump with the cold side at the ambient temperature of 25?C. Assume that the whole process is reversible and find the work input to the heat pump per kg of water.

2. Water at 1000 kPa, 200?C is brought to saturated vapor in a piston/cylinder with an isobaric process. Find the specific work and heat transfer. Estimate the specific heat transfer from the area in a T-s diagram and compare it to the correct value.
