      Do you mean why can we feel solid and liquid with our hands, but we can’t feel gas? That’s a great question! I think the answer is that the particles in gas are too spread out to have a ‘surface’, and so even though we can technically touch it, there is no clear barrier between the gas and another substance. So we just pass straight through it, with no resistance. I have never really thought about that before – interesting!
