Answer 1:
Inside a balloon there are gas molecules (oxygen, nitrogen, etc.) bouncing around and exerting pressure toward the outside of the balloon. If the balloon was not in a vacuum the gas molecules from the outside would be exerting pressure toward the balloon surface, opposing the pressure from the inside. However, there is no gas in a vacuum, therefore any pressure. So yes, you are right. The balloon exploded because of the lack of pressure in the chamber causing the balloon to expand, releasing pressure from inside. Click Here to return to the search form.
