A cylinder fitted with a frictionless, massless piston contains compressed liquid water at a temperature T1=20C. The atmospheric pressure on the outside of the system is P=1.0 bar. Heat is then added until the water is completely converted to saturated vapor.

(a) What are the changes in specific volume, v2-v1 (m3/kg) and internal energy, u2-u1 (kJ/kg) of the water for this process?

(b) How much specific work, if any, is done by the system?

(c) What is the amount of heat addition required?

(d) Carefully sketch the complete process on a T-v diagram, indicating states 1 and 2.

Water, initially (state 1) a saturated liquid at 1100C, is contained in a piston-cylinder assembly. The water undergoes a process to the corresponding saturated vapor (state 2), during which the piston moves freely in the cylinder. If the change of state is brought about by heating the water as it undergoes an internally reversible process at constant pressure and temperature, determine (a) heat transfer using first law of thermodynamics in kJ/kg and (b) heat transfer using second law of thermodynamics...
