Question

22. Which one of the following quantities can be zero on a average for the molecules of an ideal gas in
equilibrium?​

Answer 1

Explanation:

Since momentum is a vector quantity for every direction of motion of the molecules, there exists an opposite direction of motion of the other. Hence, the average momentum is zero for an ideal gas at equilibrium.

Answer 2

Answer:

since momentum is a vactor quantity for every direction of motion of the molecular,there exist an opposite direction of the other.hence,the average momentum is zero for an ideal gas at equilibrium.
