The temperature of an ideal gas is incre...

The temperature of an ideal gas is increased from `27@C " to "927@C.` The root mean square speed of its molecules becomes.

A

3 times

B

double

C

4 times

D

6 times

Text Solution

Verified by Experts

The correct Answer is:
B
From RMS speed `nu_(rms)=sqrt((3kT)/m)`
`nu_(2)/nu_(1)=sqrt((T_(2))/(T_(2)))=sqrt((273+927)/(273+27))=sqrt((1200)/(300))=2`
`nu_(2)=2nu_(1)`
