Question

A thermally insulated vessel contains an ideal gas of molecular mass M and ratio of specific heats 1.4. Vessel is moving with speed v and is suddenly brought to rest. Assuming no heat is lost to the surrounding and vessel temperature of the gas increases by : (R = universal gas constant)

Select the correct option:

$\frac{M v^2}{7 R}$

$\frac{M v^2}{5 R}$

$2 \frac{M v^2}{7 R}$

$7 \frac{\mathrm{Mv}^2}{5 \mathrm{R}}$
