# a perfect gas at apressure of 58 bar and temperature of 450k has a density of 50 kg per metre cube . the ratio of specific heat is 1.48. calculate the change in specific entropy of the gas if the pressure is raised to 100 bar and temperature is lowered to 400k

Apply the formula:-
$\fn_cm \Delta$S= CPlnT2/T- RlnP2/P1
Put the values of T2=400k
T1=450k
P2=58bar
P1=100 bar
R=1.48
