Four states of Matter


There are four states of matter. So, in this post we will learn about the states of matter.


When I, was in school i would say there are three states of matter solids, liquids and gases.Because plasma is a state which was known later.


Solids: Solids is one of the four states of matter, unlike liquid and gases, solids have a definite shape. The atoms or molecules in a solid are tied up more tightly. The atoms or molecules in a solid have fixed positions.

Liquids: Liquids don’t have a fixed shape, like a solid . The basic quality of a liquid is they can flow, the atoms and molecules are not tied up , and when a liquid boils or evaporates , it becomes gas.

Gas: Gas has the lowest density than a solid or liquid. A Quantity of gas doesn’t have a specific shape.

Plasma: When electrons are not trapped in orbits around the nucleus we call it a plasma state.

I hope this helped.
