The temperature of an ideal gas is incre...

The temperature of an ideal gas is increased from `27 ^@ C` to `927^(@)C`. The rms speed of its molecules becomes.

A

twice

B

four times

C

half

D

`sqrt(2)` times

Text Solution

Verified by Experts

The correct Answer is:
A
`(C_(1))/(C_(2))=sqrt((T_(1))/(T_(2)))=sqrt((300)/(1200))=sqrt((1)/(4))`
`(C_(1))/(C_(2))=(1)/(2)" "thereforeC_(2)=2C_(1)`.
