To what temperature should the hydrogen at room temperature `(27^(@)C)` be heahted at constant perssure so that the RMS velocity of iths molecules becomes double its previous value?

A

`1200^(@)C`

B

`927^(@)C`

C

`600^(@)C`

D

`108^(@)C`

Text Solution

Verified by Experts

The correct Answer is:
B
`nu_(rms)=sqrt((3RT)/M)impliesnu_(rms)/nu_(rms)=sqrt(T^(.)/T)implies(273+t^(.))/(273+27)=(2)^(2)=4,t^(.)=927^(@)C`
