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

A

`103^(@)C`

B

`273^(@)C`

C

`723^(@)C`

D

`819^(@)C`

Text Solution

Verified by Experts

The correct Answer is:

D

`(r_(1))/(r_(2))=sqrt((T_(2))/(T_(1)))`
`2=sqrt((T_(2))/(273))`
`T_(2)= 273xx4= 1092K= 1092-273= 819^(@)C`
