In a given gas sample of Hydrogen, one fifth of the heat supplied is used to raise the internal energy of the gas. Finding the molar specific heat of the gas gives?

$(A) 7.5R$ $(B) 6.5R$ $(C) 4.5R$ $(D) 5.5R$

Heat supplied $= n CdT$, where $C$ is the molar specific heat.
$\Rightarrow \large\frac{nCdT}{3} = \large\frac{f}{2}$$nRdT \Rightarrow C = \large\frac{3fR}{2}$$= \large\frac{15R}{2}$$= 7.5R$
