MHT CET 2024 Physics question
A 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)
Answer: (B)
Solution
When the insulated container is stopped suddenly, the ordered kinetic energy of the gas as a whole is converted into internal (thermal) energy, with no heat exchange with the surroundings. For moles of gas of molar mass : kinetic energy . The rise in internal energy at constant volume is
