Air with a dry bulb temperature of 22C and a relative humidity of 60 percent is contained in a frictionless-piston-cylinder assembly that has an initial volume of .5m^3. The air is expanded at a constant pressure of 1 atm until the dry bulb temperature reaches 35C. During this process heat is transferred to the air from a reservoir having a temperature of 80C. Determine the amount of heat transferred to the air during the process (in kilojoules) and the work.
