STATES OF MATTER

 

The states of matter refer to the physical form that matter can take. 

There are three main states of matter:

Solid: 

  • A solid has a definite shape and volume, and its particles are closely packed together and vibrate slightly.


Liquid: 

  • A liquid has a definite volume but takes the shape of its container, and its particles are more closely packed together than those in a gas but are free to move past one another.

Gas: 

  • A gas has neither a definite shape nor volume, and its particles are widely separated and in constant random motion.
