A thermally insulated vessel contains an ideal gas of molecular mass \(M\) and a specific heat ratio of \(1.4.\) The vessel is moving with speed \(v\) and is suddenly brought to rest. Assuming no heat is lost to the surroundings, then the vessel temperature of the gas increases by:
(\(R=\) universal gas constant)
1. \(\dfrac{M v^2}{7 R} \)

2. \(\dfrac{M v^2}{5 R} \)

3. \(\dfrac{2M v^2}{7 R} \)

4. \(\dfrac{7M v^2}{5 R} \)
