The average velocity of gas molecules is 400 m/sec. Calculate its rms velocity at the same temperature. |
|
Answer» Solution :`C_("rms") =SQRT((3RT)/(M)), C_("av") =sqrt((8RT)/(PI M))` `(C_("rms"))/(C_("av"))=sqrt((3RT)/(M))xx sqrt((pi M)/(8RT))=sqrt((3PI)/(8))=1.085` `C_("rms") =1.085 xx C_("av")` `=1.085xx400` `=434 MS^(-1)` |
