7.) One mole of an ideal gas is contained in an insulated piston-cylinder arrangement in an initial state T, P,V. The gas is allowed to expand adiabatically and irreversibly against a constant external pressure P. until a point is reached where the internal pressure becomes equal to Po. If C for the gas is constant and equal to 1.5 R, derive an expression giving the final temperature of the gas in terms of P., V, T, and R.

Question 1 A piston-cylinder assembly contains 3.2 kg of water at 211.9oC and 3 bar. The water is compressed to a saturated vapor state where the pressure is 51.5 bar. During compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 230 kJ. Neglecting changes in kinetic energy and potential energy, determine the work, in kJ, for the process of the water. Question 2 Water, initially saturated vapor at 10.2 bar, fills...
