Consider the following statements for air molecules in an airtight container:
(I) the average speed of molecules is larger than root mean square speed
(II) mean free path of molecules is larger than the mean distance between molecules
(III) mean free path of molecules increases with temperature
(IV) the rms speed of nitrogen molecule is smaller than oxygen molecule
The true statements are:
(I) the average speed of molecules is larger than root mean square speed
(II) mean free path of molecules is larger than the mean distance between molecules
(III) mean free path of molecules increases with temperature
(IV) the rms speed of nitrogen molecule is smaller than oxygen molecule
The true statements are:
