Question

A molecule of a gas has six degrees of freedom Then , the molar specific heat of the gas at constant volume is
A. `(R)/(2)`
B. R
C. `(3R)/(2)`
D. 3R

Answer 1

Correct Answer - D
We know that , specific heat of a gas (At Constant volume)
`c_(V)=(f)/(2)xxR`
where , R= number of independent relations
f=degree of freedom
`therefore " " C_(V)=(6)/(2)xxR=3R`
