Two and half moles of an ideal gas with cv, m=1.5r undergoes a carnot process defined by following four states: a (1.50 atm, 400 k), b (1.00 atm, 400k), c (? atm, 300 k) and d (? atm, 300 k). a) calculate q, w, au, ah and as for paths a-b, b-c, c-d and d-a. b) what is the efficiency of this carnot cycle engine with ideal gas as the working substance?
