air is composed at 1 bar and 25C up to 3 bars and 35C through a process mechanically at V=cte. Calculate the heat and work requirements, at V and H of the air for each of the paths. The following heat capacities for air are assumed to be independent of T: CV=20.785 J/molK Cp=29.1 J/molK. Assume that air remains a gas for which the PV/T ratio is a constant, regardless of the changes to which it is subjected. At 25C and 1 bar the molar volume of air is 0.02479 m3/mol. Consider the system as 1 mole of air contained in an imaginary piston/cylinder arrangement. Consider a frictionless process.
