Air & Mass Lab

Prove that air has mass, then find absolute zero from a balloon in a bucket of water. Six stations of real gas physics — weigh a pumped basketball, squeeze a sealed syringe, burst a balloon in a hot car, race three gases at one temperature — plus a sandbox where you can take any gas in any container to Mars, Everest, orbit or the Mariana Trench. Questions ask you to read your own graphs, predict values and analyse diagrams, not just pick from a list.
