Demonstrations Inside the Chamber
Gases have neither a fixed shape nor a fixed volume; they spread to fill whatever closed container holds them. Seal a partly blown-up balloon or a marshmallow in the chamber and pump: as air is removed, fewer particles strike the outside, and the air trapped inside expands until its pressure matches, so the object swells. Let air back in and it shrinks again. Warm water placed in the chamber starts to boil once the pressure falls far enough, because the boiling point drops with pressure.
Linking to the Atmosphere
Air is a mixture of nitrogen, oxygen and trace gases, including water vapour, and its pressure falls with height. Lowering the pressure in the chamber copies conditions at high altitude, which is why sealed snack packets puff up on a mountain road. Students can explain each change in terms of how the gas particles are arranged and how they move.
