is 10 times the interatomic distance
is 100 times the interatomic distance
is 1000 times the interatomic distance
is times of the interatomic distance
Get Answer
Mean free path in a gas is 100 times the interatomic distance.
Mean free path of a gas molecule is
inversely proportional to number of molecules per unit volume
inversely proportional to diameter of the molecule
directly proportional to the square root of the absolute temperature
directly proportional to the molecular mass
Mean free path,
where,
number of molecules per unit volume,
diameter of the molecules
If the pressure in a closed vessel is reduced by drawing out some gas, the mean-free path of the molecules
is decreased
is increased
remains unchanged
increases or decreases according to the nature of the gas
The number of collisions per second suffered by a molecule in a sample of hydrogen at S.T.P is:
[Mean free path ]
Calculate the value of mean free path for oxygen molecules at temperature and pressure . Assume the molecular diameter and the gas is ideal. .
Given, temperature of oxygen molecules, Pressure of oxygen
