A diatomic gas molecule has translational, rotational and vibrational degrees of freedom.
The ratio of specific heats `C_(p)/C_(v)` is

A

1.67

B

1.4

C

1.29

D

1.33

Text Solution

Verified by Experts

The correct Answer is:
B
In case of a diatomic gas,
`C_(P)= 7/2 R`
`C_(V) = 5/2 R`
`therefore C_(P)/C_(V) = 1.4`

A diatomic molecule has how many degrees of freedom

Equal volumes of two monatomic gases, A and B at same temperature and pressure are mixed. The ratio of specific heats (C_p//C_v) of the mixture will be

A gas mixture contains n_1 moles of a monoatomic gas and n_2 moles of gas of rigid diatomic molecules. Each molecule in monoatomic and diatomic gas has 3 and 5 degrees of freedom respectively. If the adiabatic exponent (C_p)/(C_v) for this gas mixture is 1.5, then the ratio n_1/n_2 will be
