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

Difficult

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

Solution

$N_{v} = 4 π N {(\frac{m}{2 π k T})}^{\frac{3}{2}} v^{2} e^{- (m v^{2} / 2 k T)}$
Where $N_{v} = \frac{d N}{d v}$ . Here, dN means number of molecules with velocities between v and v+dv.
