At what temperature, will R.M.S . velocity of hydrogen be four times of its value at N. T .P.?

A

`819^(@)C`

B

`4368^(@)C`

C

`1092^(@)C`

D

`4095^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B
`(V_(2))/(V_(1))=sqrt((T_(2))/(T_(1)))`
`(4V_(1))/(V_(1))=sqrt((T_(2))/(T_(1)))`
`16=(T_(2))/(T_(1))`
`T_(2)=16xx273=4368^(@)C`.
