Ten cubic feet of air is cooled at a constant pressure of 80 psi. The initial temperature is 180 0F and the final temperature is 100 0F. Assume air is an ideal gas, Cp = 0.241 Btu/lb 0R and Cv = 0.173 Btu/lb 0R and R = 1545 lbf/lbmol 0R, M = 28.97 lb/lbmol. The change in kinetic and potential energies is zero. Determine:

a) total mass of the air in lb

b) the work in btu

c) chage in internal energy in btu

d) heat transfer

e) change in enthalpy
