NEET Exam Model Paper 7

There is n moles of the monoatomic gas in the container.
Molar mass of the gas = m,
Total mass of the gas in the container, M = mn
Change in KE of the gas when the container is suddenly stopped, i.e.,
This change in kinetic energy (∆K) result in a change in internal energy (∆U) of the gas
∆U=nCv∆T=n(
