By what factor does the average velocity of a gaseous molecule increase when the temperature (in Kelvin) is doubled?

A

`2.8`

B

4

C

`1.4`

D

`2.0`

Text Solution

Verified by Experts

The correct Answer is:
C
`"Average velocity"=sqrt((8RT)/(piM))`
`therefore" "V_(av) propsqrtT" or "((V_(av))_(2))/((V_(av))_(1))=sqrt((2T)/(T))=1.4`
