Matter:
- Matter is anything that has mass and takes up space.
- It is the physical material that makes up everything in the universe, including solids, liquids, and gases.
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.
