By what factor does average velocity of a gas molecule increase when temperature (in K) is doubled-

A

2

B

2.8

C

4

D

1.4

Text Solution

Verified by Experts

The correct Answer is:
D
`overline(c)=sqrt((8RT)/(piM))`
When T is doubled, `overline(c)_(1)=sqrt((8Rxx2T)/(piM))=sqrt(2)sqrt((8R)/(piM))`
`therefore overline(c)_(1)=sqrt(2)overline(c)=1.4overline(c)`.
