At what temperature rms speed of air molecules is doubled of that at NTP ?

A

`819^(@)C`

B

`719^(@)C`

C

`909^(@)C`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
we have `v"rms"propsqrtT`
`rArr" " (v_(1)^(2))/(v_(2)^(2))=(T_(1))/(T_(2))rArr(v^(2))/(4v^(2))=(273)/(T_(2))`
`rArr"Temperature "T_(2)=1092K=819^(@)C`
