Question

The most probable speed of the molecules is 1029 m/s. The root mean square velocity of the molecules of a gas is
a)1029m/s
b)2160m/s
c)1260m/s
d)514.4m/s



please help me out ​

Answer 1

Given:

The most probable speed of the molecules = 1029 m/s

To find:

The root mean square velocity of the molecules of the gas.

Solution:

The root mean square velocity is always less than the most probable speed hence in this case, the root mean square velocity of the molecule will be 514.4 m/s which is less than 1209 m/s.

Thus, the root mean square velocity of the molecule will be 514.4 m/s.
