Water is a special kind of liquid. It's different from most other liquids because it does some really cool things.
Water has the ability to change shape when it goes from a liquid to a gas. This means that water can become steam and can be seen as tiny droplets in the air.
Water also has the ability to hold a lot of heat. This is why it takes a long time to heat up or cool down a big pool of water.
Water has a very high surface tension. This means that water droplets can hold their shape, and it also allows water to flow up a narrow tube.
Water also has a very high specific heat. This means that if you heat one kilogram of water, it takes a lot of energy to do it. Heat will “stick” to the water and make it very difficult to get rid of.
Finally, water is a very good solvent. This means that a lot of other substances can dissolve in water, like sugar or salt.
