I am not sure if my work is correct so I need your help to confirm it.
Question:
Find the change in entropy when:
n mol of ideal gas (ɣ=7/5) is reversibly compressed until the pressure is three times the ideal gas at constant temperature.
My answer:
S=n Cv ln(T2/T1) + nR ln(V2/V1)
as temperature is constant so
S=nR ln(V2/V1)
V2/V1=1/3
