(Atoms molecules) Auz like molecules of same gas are identical in all respects (maas. shape, size) molecules are constantly in random motion along Straight Line. ALL the collisions of gas molecules among themselves & with wall of container is Elastic in nature. The pressure of a gas is due to collision of molecules with wall of condainer.

(Absolute) the volume occupied by gas molecules is negligible when compared to volume of gas. ARiHANT usloof [uol. of molecules.
