Answer:
It is important to understand the particle nature of matter. ... The particles that make up matter are not 'small bits of solid' or 'small drops of liquid' but atoms and molecules. The physical characteristics of those atoms and molecules decide its state.Water is very convenient for explaining changes of state. We see water as solid, liquid and as a gas in daily life. ... We can go in the other direction, by condensing steam to liquid and freezing liquid to iceIt's important for scientists to know the properties of matter because all things are made up of matter. Each type of matter has different physical characteristics and scientists need to know and understand these characteristics to make calculations.
States of matter
Solids – relatively rigid, definite volume and shape. In a solid, the atoms and molecules are attached to each other. ...
Liquids – definite volume but able to change shape by flowing. In a liquid, the atoms and molecules are loosely bonded. ...
Gases – no definite volume or shape.
Bose–Einstein condensate.
Fermionic condensate.
Degenerate matter.
Quantum Hall.
Rydberg matter.
Rydberg polaron.
Strange matter.
Superfluid.
