DOUBT Sir in one of the question you upload on yt Q: P-V diagram of a diatomic gas is a straight line passing through origin. The molar heat capacity of the gas in the process will be (a) 4R (b) 2.5 R (c) 3R (d) 4R/ 3 Solution Cp - Cv = R/2 CP - cv = R/2 CP - 5R/2 = R/2 Then cp = 3R BUT IF WE SOLVE Cp/Cv = r Cv = Cp/r Now by putting this equation we get Cp - Cv = R/2 Cp - cp/r = R/2 Cp [1 - 1/r] = R/2 By putting the value of r = 7/5 Then cp [2/7] = R/2 Cp = 7R/4 How ??? Please solve my doubt
Thanks sir🙏

Sir in one of the question you upload on yt
Q: P-V diagram of a diatomic gas is a straight line passing through origin. The molar heat capacity of the gas in the process will be
(a) 4R
(b) 2.5 R
(c) 3R
(d) 4R/ 3
Solution
Cp - Cv = R/2
CP - cv = R/2
CP - 5R/2 = R/2
Then cp = 3R
BUT IF WE SOLVE
Cp/Cv = r
Cv = Cp/r
Now by putting this equation we get
Cp - Cv = R/2
Cp - cp/r = R/2
Cp [1 - 1/r] = R/2
By putting the value of r = 7/5
Then cp [2/7] = R/2
Cp = 7R/4
How ???
Please solve my doubt

Thank you sir but jab hum Cv ki value in terms of gamma(r) likhe hai to incorrect ku aa raha hai please explain.
