a quantity of a gas occupies 0.14 m cube at 9.65 bar and 371 degrees Celsius is heated during a constant volume process and the pressure reaches 41.4 bar. The gas is then expanded adiabatically to a pressure of 2.76 bar. Given that R is equal to 0.288 kilo joules per kilogram Kelvin and Gamma is equal to 1.41, calculate:
a) the temperature at the beginning of the expansion
b) the temperature at the end of the expansion
c) the heat energy supplied
d) the work energy transferred

a) The temperature at the beginning can be found from the condition
T1p1V1=T2p2V2,
where
V1=V2:
T1p1=T2p2,T2=T1p1p2=2763 K.
Hot!
b) The adiabatic law (and keep in mind that for isochoric processV1=V2):
