The average speed of an ideal gas molecule at `27^(@)C` is `0.3 m, sec^(-1)`. The average speed at `927^(@)C`

A

`0.15 m sec^(-1)`

B

`0.6 m sec^(-1)`

C

`1.2 m sec^(-1)`

D

`0.6 cm sec^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`U_(AVg)=sqrt((8RT)/(pi M))implies (U_(AVg.))/(0.3)=sqrt((1200)/(300))`
`U_(AVg).= 0.6 m//sec`
