Questions  

As per Maxwell’s law of distribution of velocities of molecules of an ideal gas,

a
Range of speeds of molecules increases as temperature is increased
b
Fraction of molecules having most probable velocity decreases as temperature  is increased
c
Numbers of molecules having too low or too high velocities are low compared to  number of molecules with intermediate velocities
d
All of the above

detailed solution

Correct option is D

Nv=4πNm2πkT32v2e−mv2/2kTWhere  Nv=dNdv. Here, dN means number of molecules with velocities between v  and  v+dv.
