Question

(MCQ)-the root mean square speed (c,rms) of a gas is:- a) proportional to the temperature of the gas b) proportional to the molar mass of the gas c) inversely proportional to the gas constant d) not related to the temperature and molar mass of the gas

Answer 1

i think (a) proportional to tha temperature of tha gas

Answer 2

root-mean-square velocity v(rms), of the molecules of the gas is proportional to the square root of its molar mass.
The root-mean-square speed measures the average speed of particles in a gas, defined as vrms=√3RT/M
