Solution

## The correct option is D 38NakB(T2−T1)The process is being completed at a constant volume because the volume of the container is fixed. so the heat energy required will be Q=nCvΔTWhere Cv is specific heat at constant volume and n is number of moles given by n=1gm4gm/mole=14moleand the specific heat is given as Cv=fNakB2The degree of freedom, f has value 3 for a mono-atomic gas.Na is Avogadro Number and kB is Boltzman's constant putting all above values in the expression for Q we get Q=38NakBΔT=38NakB(T2−T1)Option D is correct.
