Answer to Question #136339 in Molecular Physics | Thermodynamics for Sneha

Question

What is root mean square velocit.

Answer 1

Solution

According to kinetic theory of gases  square root of the mean of squares of the velocity of individual gas molecules this term is known as root mean square velocity.if any gas R is gas constant, T is temperature is kelvin,m is molar mass of gas then root mean square velocity is written as

$V_{rms}= \sqrt{\frac {3RT}{m}}$
