If the absolute temperature of a gas is increased 3 times the rms velocity of the molecules will be ............. .

Answer»

3 TIMES
9 times
`sqrt3`times
`sqrt6`times

Solution :`V_(rms) = SQRT(KT)`
`V_(rms1) = sqrt(KT) , V_(rms2) = sqrt(3KT)`
`(V_(rms2))/(V_(rms1)) = (sqrt(3KT))/(sqrt(KT)) = sqrt3`
`V_(rms2) = sqrt3 V_(rms1)`
