Gas pressure

Summary: When you blow up a balloon,there are millions of air moleculeshitting the inside of the balloon. The collisions (hits) between the airmolecules and the balloon producegas pressure (air pressure). Lots ofcollisions per second make a high gas pressure. This is because there is a big force over a small area. Gas pressure is exerted (applied) in all directions. Tags: science student-book-7 physics Created: 2026-05-21 Last Updated: 2026-05-21
