By what factor does the average velocity of a gaseous molecule increase when the absolute temperature 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 of a gas `= sqrt((8RT)/( pi M ))`
`v prop sqrt( T )`
When temperature of a gas is doubled, its average velocity becomes `sqrt(2)` times i.e., 1.414 times.
