Let `barv,v_(rms) and v_p` respectively denote the mean speed. Root mean square speed, and most probable speed of the molecules in an ideal monoatomic gas at absolute temperature T. The mass of a molecule is m. Then

A

No molecule can have speed greater than `v_("rms")`

B

No molecule can have speed less than `(v_(p))/(sqrt(2))`

C

`v_(p) lt overlinev lt v_("rms")`

D

The average kinetic energy of a molecule is `(3)/(4) mv_(p)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
C, D

`v_(p) = sqrt((2RT)/(M)) , overlinev = sqrt((8RT)/(piM)), v_(rms) = sqrt((3RT)/(M))`
