Facts About Liquids for Kids to Know

Anything that has weight and takes space is called matter. The liquid is a state of matter that is neither hard like a solid nor as compressible as gas. But what is liquid in science? A liquid in science is anything that has a definite volume but no definite shape and conforms to the shape of the container that it is kept in.

States of Matter

What is Liquid?

The liquid is a state of matter made of small particles that are distant from each other. Let us see some pictures of liquid matter.

Particles in a Liquid

These particles are not arranged in a specific pattern, so they can move around and past each other. Liquids can be changed into solids and gases depending on temperature and pressure.

• The process in which a solid turn into liquid is called melting.

• The process in which a liquid turns into gas is called evaporation.

• When a liquid turns into a solid, the process is called freezing.

• When a gas turns into a liquid state, the process is called condensation.

Examples of Liquid 

Some examples of liquids are as follows:

• Water - Water is found all over the world, in oceans, seas, rivers, in the form of rain, etc.

• Honey - Honey comes from bees and is found as a liquid in hives.

Honey

• Blood - The blood in our body is also in the form of liquid.

Other examples of liquid are juice, milk, oil, etc.

Facts About Liquid State of Matter

• Liquids don't have a proper shape. They take the shape of the containers they are kept in. Without a container, they form a pool or puddle.

Liquids Take the Shape of their Container

• Some liquids do not mix. For example, oil and water, liquid wax and water.

Oil and Water do not Mix

• Mercury is the only metal in the form of liquid at room temperature.

Mercury is a Liquid Metal

• Dissolving is turning a solid into a liquid, like sugar in water.

• Water, when frozen, turns into ice, which is solid. If water is boiled, it turns into vapour which is in a gaseous state.

• A liquid can be weighed to find out how heavy it is.

Properties of Liquids

• Liquids do not have a definite shape but take the shape of their containers.

• Liquids can flow, and this ability is called viscosity.

• Liquids have a fixed volume.

• Liquids can be compressed under huge pressure.

Summary

We have learnt some interesting information about liquids and other states of matter. The matter is everything that you can see, feel and touch around you. A liquid is a state of matter that has size or volume but does not have a shape. It can flow. It takes the shape of its container. Examples of liquid are water, milk, oil, juice, etc.
