Questions
The root mean square velocity of the gas molecules is 300 m/s. What will be the root mean square speed of the molecules if the atomic weight is double and absolute temperature is halved?
detailed solution
Correct option is B
vrms=3RTMOr 300=3RTMAndvrms'=3R(T/2)2M=12×300=150 m/sTalk to our academic expert!
