Question

(e) 0.5kg of air is expanded according to the law PV^(12)= constant from initial conditions of a pressure of 1.4MN/m^(2) and a volume of 0.06m^(3) to a finite pressure of 0.35MN/m^(2) . Assume c_(mu)=1.006k//kgK and c_(v)=0.717kJ/kgK Calculate not using Entropy values the heat transferred in kJ by the air during the expansion. Show that the amount of heat transfer calculated in (1) above is approximately equal to the change of entropy multiplied by the mean absolute temperature State your answer in kJ .​
