A thermally insulated vessel contains an ideal gas of molecular mass M and ratio of specific heats 1.4. Vessel is moving with speed $\displaystyle v$ and is suddenly brought to rest. Assuming no heat is lost to the surrounding and vessel temperature of the gas increases by :
$\displaystyle (\mathrm{R}=$ universal gas constant $\displaystyle )$
Official answer
(2)
$\displaystyle \frac{\mathrm{M} v^2}{5 \mathrm{R}}$
