According to Kinetic Theory, the molecules of a gas at given temp:
a) all move with speed Vrms
b) all move at speeds greater than Vrms
c) speeds less than Vrms
d) above, at, or below Vrms
e) none

i think its D as Vrms is an average but i am not sure

Answer 1

The answer is (d), although Vrms is the square root of the average of the square of V, which is not the same thing as the average speed
