The temperature at which the `rms` speed of air molecules is double of that at `STP` is

A

`819^(@)`

B

`819 K`

C

`1092^(@)C`

D

`1192 K`

Text Solution

Verified by Experts

The correct Answer is:
A

`(v'_(rms))/(v_(rms)) = sqrt((T')/(T))`
`2 = sqrt((T')/(273)) rArr T' = 1092 k`
`T' = 1092 - 273 = 819^(@)C`
