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

A

1.4

B

`2.0`

C

`2.8`

D

`4.0`

Text Solution

Verified by Experts

The correct Answer is:
A
Average velocity `(vecc)=sqrt((8RT)/(piM))`
If absolute temperature is doubled, new average velocity `=sqrt((8R.2T)/(piM))=sqrt(2)bar(c )=1.4bar(c )`
