A sample of gas is at `0^(@)C`. The temperature at which its rms speed of the molecule will be doubled is

A

`273^(@)C`

B

`623^(@)C`

C

`819^(@)C`

D

`1092^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
C
`C_(2)/C_(1)=sqrt(T_(2)/T_(1))" "therefore4=T_(2)/T_(1)`
`thereforeT_(2)=273xx4=1092" "thereforeT_(1)=1092-273=819^(@)C`
