Five kilograms of air has a pressure of 200 kPa at temperature of 27 ° C. It is heated at constant pressure to reach a temperature of 227 ° C. It is then brought reversibly and isothermally to the final pressure 100 kPa. Assume air as ideal gas and has an average CP = 1.005 kJ / kg K. The gas constant for air is Rair -0.286 kJ / kg - K. Calculate the entropy change from state 1 to state 3.

A quantity of an ideal gas in an isolated system expanded isothermally and reversibly at 400 K from a volume V1 to a volume V2. During the expansion, the gas absorbs 200 J of heat from the reservoir in contact with it.

Two containers, A and B, are separated by a division. Initially, Tank A contains 5lb of water at 170Psia and 600 ° F, while Vessel B contains 7lb of water, at 300 ° F, with 60% mass fraction of vapor. The division is then removed, and the two sides are allowed to mix, until mechanical and thermal equilibrium is established. If the end-state pressure is 60 Psia, determine the entropy change in the system. Note : dear expect please mention which property table you used
