N molecules of a gas have speeds 1,2,3....Nm/s respectively.The ratio of rms speed to average speed is

Five molecules of a gas have speeds 1,2,3,4 and 5km/sec .The ratio of their rms speed and average speed is

Four molecules of a gas have speed 1, 2, 3 and 4 km s^(-1) respectively. The value of rms speed of the molecules is (in km s^(-1) )

Five molecules of gas have velocities 10,20,30,40 and 50 m/s. The ratio of R.M.S speed to average speed is

Four molecules of a gas have speeds 2, 4, 6 and 8 kms^(-1) respectively. Calculate their average speed and root mean square speed.

Five molecules of a gas have speeds 1, 1, 3, 3, 2 km/s the value of the r.m.s spreed of the gas molecules is

If C_(1), C_(2), C_(3) ......are random speed of gas molecules, then average speed C_(av)= (C_(1)+C_(2)+C_(3)+...C_(n))/(n) and root mean square speed of gas molecules, C_(rms) = sqrt((C_(1)^(2)+C_(2)^(2)+C_(3)^(2)+...C_(n)^(2))/(n)) =C . Further , C_(2) prop T or C prop sqrt(T) at 0k, C=0 , ie., molecular motion stops. With the help of the passage given above , choose the most appropriate alternative for each of the following question: If three molecules have velocities 0.5, 1 and 2km//s , the ratio of rms speed and average speed is

Four molecules of a gas have velocity 2, 4, 6 and 8 kms^(-1) , respectively. The ratio of their root mean velocity and average speed is :

The speeds of 4 molecules of a gas in arbitary units are 2, 3, 4 and 5. what is the ratio of rms speed and mean speed of the gas molecules.
