Question:
An insulated container containing monoatomic gas of molar mass m is moving with a velocity vo. If the container is suddenly stopped, find the change in temperature.
Solution:
The final KE of the gas = 0
Change in KE, ∆K= 1/2 (nm)v2
∆T is the change in the temperature
∆U = nCv∆T
∆K = ∆U
∆T = mv02/3R
