In Chemistry, I have learnt that the particles in a gas are far apart. Hence the particles in the air around me are far apart. But if there are no particles in the spaces,it means no matter exists. read more
What we call the ‘air’, is the gas particles themselves: which include nitrogen, oxygen, argon, carbon dioxide, water vapor, trace amounts of other gases, dust and pollutants. read more
When you take into account how gas molecules interact (London dispersion force, induced dipoles and attraction and repulsion between molecules) it doesn't change this distribution much, but it does change how well it fits the ideal gas law ( PV = nkT, or mechanical energy = random thermal kinetic energy ) since there is potential energy in the attraction and repulsion. read more
