Question
In a certain gas, the ratio of the speed of sound and root mean square speed is 
. The molar heat capacity of the gas in a process given by PT = constant is (Take R = 2 cal/mole K). Treat the gas as ideal.
. The molar heat capacity of the gas in a process given by PT = constant is (Take R = 2 cal/mole K). Treat the gas as ideal.Options
A.
B.
C.
D.
Solution
(D)
[Monoatomic gas]
PT = const
P2V = const ⇒ PV1/2 = const
⇒ x =
⇒ C = CV + 
= 
R + 2R =
