Different Gases
In Air Has Weight, weigh an empty PET bottle against one pumped full of air — the number on the scale proves that invisible air really does weigh something. In Bigger, Smaller, heat a balloon and watch it swell, press it and watch it shrink, then move the scene deep underwater or up a mountain to see pressure change its volume too. In Which Gas Is It?, run tests on oxygen, carbon dioxide, nitrogen, and helium one by one to tell them apart and learn what each is used for. Invisible doesn't mean nonexistent — weight and volume make air's behavior visible.
Boyle's Law
🔽 Add weights on the cylinder and watch the gas shrink in volume! With 2 weights it becomes half, with 3 it becomes 1/3. But multiply pressure by volume, and it always equals 60. Even across 6 steps, this value stays steady with all 12 particles simply squeezed closer together. 🔥 Let's heat it up! Every 20 degrees, volume grows by 2. The particles didn't multiply—they just moved faster to push the piston up. 🎈 Look at real life: a snack bag puffs up on a high mountain, while air bubbles shrink deep underwater. But what about a stiff can near a fire? Its volume can't expand, so pressure spikes instead! Built with code · Remix it to add your own experiments!
