If average velocity of a sample of gas molecules at 300 K is 5 cm s-1, what is RMS velocity of same sample of gas molecules at the same temperature? (Given, : : u v 1 : 1.224 : 1.127) (most probable velocity), u(RMS velocity), v (average velocity) (MHT CET 2014)
A.6.112 cm/s
B.4.605 cm/s
C.4.085 cm/s (d) 5.430 cm/s
Explanation
Given that (most probable velocity) : u(RMS velocity) : v (average velocity) = 1 : 1.224 : 1.127 1.224 1.224 1.127 5 1.127 u >> 1.224 5 5.430 / 1.127 u cm s x >>
