The ratio of root mean square velocity of average velocity of a gas molecule at a particular temperture is

A

`1.086 :1`

B

`1:1.086`

C

`2:1.086`

D

`1.086:2`

Text Solution

Verified by Experts

The correct Answer is:
A
`u_("rms")=sqrt((3RT)/M),u_(av)=sqrt((8RT)/(piM)) , (u_(rms))/(u_(av))= sqrt((3pi)/8)`
`=sqrt(66/56) rArr (1.086)/1 `.
