MCQ

The root mean square velocity of molecules of gas is

A
Proportional to square of temperature $\left( T ^2\right)$.
B
Inversely proportional to square root of temperature $\sqrt{\frac{1}{ T }}$.
✓
Proportional to square root of temperature $\sqrt{T}$.
D
Proportional to temperature $(T)$.

✓

Answer

Correct option: C.

Proportional to square root of temperature $\sqrt{T}$.

c
The rms speed of a gas molecule is

$V _{ RMS }=\sqrt{\frac{3 RT }{ M }}$

$V _{ RMS } \alpha \sqrt{ T }$
