An Introduction to States of Matter
Water can exist as ice, liquid, and even vapours which means it can exist in variable states. Have you ever wondered how some objects are rigid whereas others are easily changing their shape? This is all due to the state in which a matter exists. Variable states provide various properties to any matter.
States of the Matter
States of matter means different or distinct characteristics and properties a matter can exhibit. It is also known as the phases of matter. In general, there are three states of matter, i.e., solid, liquid, and gas. Every state of matter has unique properties in very different environmental conditions which form the basis of the classification. Every state of matter is exhibited around us from a solid sofa to liquid cold drinks and from water to gaseous air that we breathe. Every state of matter has an essential part in the environment and our day-to-day life.
Solids, Liquids, and Gases
Solids are tough and have a rigid shape which implies that they cannot be moulded into other shapes easily.
They occupy a definite space.
Have a fixed shape and volume.
Have high intermolecular attraction and less or no space between consecutive molecules which provides them rigidity.
Do not tend to flow like liquids and cannot be easily compressed.
Example - wood, ice, brick, stone.
Examples of Solids
Liquids have fixed volume but do not have a fixed shape. They occupy space and change their shape according to the container they are placed in.
They have a higher density, and more intermolecular space between them, unlike solids.
The liquid particles can flow easily and freely.
Can be compressed to a certain extent.
Examples - blood, water, milk, coffee.
Examples of Liquids
They neither have a fixed volume nor a fixed shape.
They have much less intermolecular space between them compared to solids as well as liquids.
Gases are easily liquified or compressed.
They fill the space complete in which they are kept.
Particles have very little interaction and are randomly moving.
Examples - oxygen, carbon dioxide, neon, etc.
Examples of Gaseous State
Differences between Different States of Matter
Difference between Solids and Liquids
There are three states of matter that exist in distinct physical forms under different environmental conditions. These matters are usually classified according to the basis of intermolecular forces and space between the molecules. These states can be changed into each other by various processes.
