Important Physical Properties of matter
- Matter is made up of particles
- The particles are very small in size
- These particles have spaces between them
- These particles are constantly moving
- Particles attract each other
- There are 3 states of Matter - Solids, Liquids and Gases
- Matter can change state from one form to another
Old and New School of Thought
As per Old School of thought
-
Matter is Made up of continuous particles
Example like a block of wood
As per New school of thought
- Matter is made up of small particles like sand
Difference between Physical and Chemical Properties

CHEMICAL PROPERTIES |
|
Properties that can be measured without changing the composition of the substance |
Properties that define the ability of a substance to react and form new substances |
|
These include color, malleability, ductility, conductivity, hardness, melting point, boiling point, density |
These include rusting, burning, rotting, oxidizing, reducing, decomposing, exploding |

Summary
Hence, we can see matter is made up of small particles.
- Some of these particles mix with each other o r dissolve with each other
- But particles in some objects cannot mix - like wood and salt won't mix
Lets look at the Characteristics of Particles of Matter
