Suppose that molecules of a gas lost a small fraction of their kinetic energy in every collision (inelastic collisions). For an insulated sample of this gas, with time:
Options:
Answer:
A
Solution:
The total translational energy would keep dropping, so the average speed and hence the temperature would fall. The pressure, which is proportional to the mean kinetic energy per volume, would fall too. A.
