1. Schritt 1. Spirit level — nutzt — Universal gravitation. The bubble rises to the highest point.
2. Schritt 2. Universal gravitation — wird verwendet in — Hydroelectric power station. The energy of falling water.
3. Schritt 3. Hydroelectric power station — funktioniert wie — Wave power station. A wave power station, like a hydro plant, draws energy from water — waves instead of a river.
4. Schritt 4. Wave power station — nutzt — Hydraulics (Pascal’s law). Hydraulic converters.
5. Schritt 5. Hydraulics (Pascal’s law) — wird verwendet in — Manometer. A liquid manometer is a pair of communicating vessels: the difference in levels shows the pressure.
6. Schritt 6. Manometer — ist Teil von — Autoklav. The gauge shows whether the steam pressure in the chamber is high enough to sterilize.
