Question

The temperature of an ideal gas is
increased
from 140 K to 560 K. If at 140 K the root
mean square velocity of the gas molecules
is u, at 560 K it becomes
(1) 5u
(2) 2u
(3) u/2
(4) u/4​

Answer 1

Answer:

The root mean square velocity is directly proportional to the square root of temperature.

Thus when the temperature increases from 140 K to 560 K, the root mean square velocity increases from u to

140

560

u=2u.
