Imagine that both of these balloons are tighly sealed. By the next day, the helium-filled balloon has become much smaller than the oxygen-filled balloon. If the temperature and pressuew in the room did not change, Why do you think this happened??? PLEASE HELP ME. I think that you need to use kinetic molecular theory I do remember that helium atoms are smaller than oxygen molecules if this helps,
