Estimate the number of collisions per second suffered by a molecule in a sample of hydrogen at STP.The mean free path (average distance covered by a molecule between successive collisions)=1.38xx10^(-5)cm.`

The distance travelled by a molecule between two successive collisions is called as

The distance travelled by a molecule between two successive collisions is called as

What do you call the straight line path described by a gas molecule between two successive collisions?

(A): Mean free path of gas molecules, varies inversely as density of the gas. (R): Mean free path of gas molecules is defined as the average distance travelled by a molecule between two successive collisions.

For a molecule of diameter 2.5 Å and number density of molecule 2.1 xx 10^(25) molecule /m^(3) , calculate average distance (mean free path) covered by a molecule between two successive collisions.

Statement I: Mean free path of gas molecules,varies inversely with density of the gas Statement II: Mean free path of gas molecule is defined as the average distance travelled by a molecule between two successive collisions.

Average straight distance covered between two successive collision of molecules is called………………….

The resistivity of material of a wire is 2xx10^(-8) Omegam and the number of free electrons per unit volume is 9xx10^(28) per m^3 . Calculate the relaxation time which is defined as the average time interval between two successive collisions. Also calculate the mean free path of electron (distance covered by electron between two successive collisions) if the drift velocity of electrons is 1.7 xx10^(-4)m//s .

As the speed of molecules increase, the number of collisions per second :
