What are the effects of Intermolecular forces on real gases and the conditions under which these effects become most evident? Molecules in real gases do not completely obey the ideal gas laws because the molecules are subjected to intermolecular forces known as ATTRACTIONS and REPULSIONS. These effects are typically seen under conditions of HIGH and […]
