Average velocity of molecules of a gas in a container, moving only in one dimension, is
Options:
Answer:
C
Solution:
Velocity is a vector. Even restricted to one dimension, molecules move equally in the + and - directions, so the vector sum cancels: langle v rangle = 0. (√(8RT/π M) is the mean speed, a scalar, not the mean velocity.) Confirms Ans (c) Zero.
