The temperature of an ideal gas increase...

The temperature of an ideal gas increased from 120 k to 480 k. The root mean square velocity of the gas molecules is 'v', at 480 K it becomes

Text Solution

Verified by Experts

`because V_(rms)=sqrt((3RT)/(M_w)) thereforeV_(rms)prop sqrtT`
`therefore(V_(rms))_(T_2)=vxxsqrt((480)/(120))=2v, (V_(rms))_(T_2)=2v`
