Chemistry - Thermodynamics - I Question with Solution | TestHub

$5$moles of an ideal gas at$100\mathrm{ }\mathrm{K}$are allowed to undergo reversible compression till its temperature becomes$200\mathrm{ }\mathrm{K}.$If${\mathrm{C}}_{\mathrm{V}}=28\mathrm{ }\mathrm{J}\mathrm{ }{\mathrm{K}}^{-1},$calculate$∆\mathrm{U}$and$∆\mathrm{p}\mathrm{V}$for the process.$(\mathrm{R}=8.0\mathrm{ }\mathrm{J}\mathrm{ }{\mathrm{K}}^{-1}\mathrm{ }\mathrm{m}\mathrm{o}{\mathrm{l}}^{-1})$
