Gases - Chemistry Study Notes

muck upes obligate is exerted by gas particles hitting the walls of the containerweakest intermolecular push back (hydrogen) --> out of all the gases going to nearly obey ?Gas particles neither attract nor repel each other? (#3 of kinetic theory of gases)PressureWhy is billping on a nail more(prenominal) painful than lying on a make love of nails?-force exerted by your mass is spread out over a big state (when one lies on a freighter of nails) compared to when you step on a nail, so you feel little pain.
