    Air behaves in the same way as any other fluid (wē). It flows and spreads into spaces that are not otherwise occupied. Unlike a fluid, however, it can be squashed (compressed). When a bike tyre is pumped up, more and more air is pushed in to that space, and the air is spread evenly throughout the space but under increasing pressure.
