A substance has constant heat capacity CP = 3.5R and its equation of state is given by:
P (V-cRT) = RT
where c = 5 * 10-7 m3 /J. This substance is isentropically compressed from P1 =1 bar, T1= 300 K to P2= 5 bar. What is the temperature after compression?
(An "isentropic process" is one in which the entropy of the fluid remains constant.)
