Water is so important to our life. Let’s learn five legendary liquids facts for kids.
Liquids can take the shape of the container into which they are poured because they are free-flowing. Liquids have a fixed volume but no fixed shape. The molecules in a liquid have a much greater freedom to move around than those of a solid.
Water is a liquid and without water we can not survive. Hydration is essential for us to be able to live. If we stopped drinking water we would become dehydrated. Dehydration is very serious and if symptoms prolong it can lead to life-threatening complications such as kidney failure. The maximum time a person can live without water is less than a week and can be as short as two days, depending on what environment they are in. Water is far more essential to our bodies than food.
Different liquids have different freezing and boiling points depending on the different forces between molecules. Some liquid molecules have stronger forces holding molecules to each other than other kinds of molecules. The heavier the particles in the liquid, and the stronger the bonding, the higher the boiling point will be. The boiling point for water is 100°C, whereas the boiling point for liquid helium is -268.95°C. The temperature at which a liquid becomes a solid is the freezing point. The freezing point for water is 0°C, whereas liquid Nitrogen has a freezing point of -210°C.
Liquids cannot be compressed because they have a fixed volume. It would take a great deal of pressure to compress a liquid and for that reason they are said to be incompressible. When you compress a liquid, its viscosity increases as the density increases. Viscosity is the resistance of the liquid to flow, or the consistency of a liquid. A liquid with less viscosity is water and a liquid with very thick viscosity is honey.
The two types of liquids are liquid mixtures and pure liquids. Pure liquids are liquids that they boil at a precisely constant temperature. Examples of pure liquids are water, ethanol and mercury. A liquid mixture is two or more liquids mixed together. These liquids may be of different consistencies. An example of different liquid mixtures are water and oil. Liquids can be separated from solids through evaporation and filtration.
We hope you enjoyed learning more things about liquids as much as we loved teaching you about them. Now that you know how majestic the universe is, you can move on to learn about other STEM articles like: Gases and States of Matter.
