In previous, Find the value of `gamma = C_(P) // C_(v) :`

A

1.6

B

1.5

C

1.6

D

1.66

Text Solution

Verified by Experts

The correct Answer is:
D
d. Straight line represents the constant pressure
`W_(12) = 0`
`dQ = n_(P). dT implies dU = nC_(v) dT`
`dW = n (C_(P) - C_(v)) dT`
`(dQ)/(dW) = (5)/(2) = (nC_(P) . dT)/(n (C_(P) - C_(v)) dT`
`= (1)/(1 - C_(v)//C_(P)) = (gamma)/(gamma - 1)`
`gamma = (5)/(3) = 1.66`
