19.48. Three moles of an ideal
gas are taken around the cycle
abc shown in Fig. 19.31. For
this gas, C_(p)=29.1(J)/(m)ol*K.
Process ac is at constant pres-
sure, process ba is at constant
volume, and process cb is adia-
batic. The temperatures of the
gas in states a,c, and b are
T_(a)=300K,T_(c)=492K, and
T_(b)=600K. Calculate the total
