An insulated container contains a diatomic gas of molar mass ' m '. The container is moving with velocity ' V ', if it is stopped suddenly, the change in temperature is ( R = gas constant)

Step-by-step solution

Kinetic energy of gas =n ( 1 2 m V^2 ) The change in internal energy when the box is stopped suddenly is, U = nC _ v ~T For diatomic gas, C _ v = 5 2 R As the energy is conserved, U = K . E . So, from above equations, array ll & n 5 2 R T=n ( 1 2 mV ^2 ) & T = mV ^2 5 R array
