The velocity of 10 gas molecules is a container are 2,3,3,4,4,4,5,5,7 and `10 km.s^-1` respectively. Find out the mean velocity and rms speed.

Text Solution

Verified by Experts

Mean velocity
`vecc=(2+3+3+4+4+4+5+5+7+10)/10=47/10`
`=4.7km.s^-1`
rms speed
`vecc=sqrt((2^2+3^2+3^2+4^2+4^2+4^2+5^2+5^2+7^2+10^2)/10)`
`sqrt(269/10)=sqrt26.9=5.1865 km.s^-1`
