The temperature of an ideal gas is increased from $120 K$ to $480 K$ . If at $120 K$ , the root mean square velocity of the gas molecules is $v$ , at $480 K$ it becomes

Options:

Answer:

Solution:

$\frac{v _{1}}{v _{2}} = \frac{\frac{3 RT _{1}}{M}}{\frac{3 RT _{2}}{M}} = \frac{T _{1}}{T _{2}} ∴ v_{2} = 2 v_{1}$
