If you want to compress water or other liquids, you won’t have it easy. This practical tip explains why this is so.
Physical Properties of Water
Water consists of two hydrogens and one oxygen atom (H2O for short). Water is mostly found in a liquid state, but depending on its state of aggregation it can change from gaseous to vapor or solid to ice.
- Water has its greatest density at three to four degrees Celsius. After that, it cannot be further compressed.
- On the contrary, it even expands again when it solidifies. You can observe this when you put a plastic bottle filled with water in the freezer.
- The gases oxygen and hydrogen can be highly compressed, so that they can be used for diving, for example, or could be used as fuel for cars in the future.
- Water, on the other hand, can hardly be compressed. But that also has its advantages.
Hydraulics
Since water cannot be compressed very much and would eventually look for a way to get out of its “prison”, this property can be used well to lift heavy objects or to press bulky objects.
- Hydraulics uses the low compressibility of water in aircraft for flaps and in cars for brakes or convertible roofs.
- For your safety, brakes must be bled regularly, otherwise, they lose their braking effect.
- Unfortunately, compressed water can’t save you from lugging the water boxes or saving space.
