​Essential Question:

​

How does the motion of particles differ in a solid, liquid, and gas?​

​What is Matter?

Matter is anything that has mass and takes up space (volume).

​

Examples: desk, chairs, books, water, air, gatorade, ANYTHING​

​Matter is divided into 4 categories:

​

​It depends on the way the particles move

​ Solids

-Any matter that has a definite (rigid) shape and definite volume.​

​

​-The particles vibrate next to each other.

​

-The particles are tightly packed.​

​

Examples: books, chairs, tables​

​

​There are two types of Solids:

1) Crystalline Solid- particles are in regular pattern.

examples: sugar, salt

​

2)Amorphous Solid​-particles are not arranged in a regular pattern.

examples: butter​

​

​ Liquids

-Matter that has a definite volume, but indefinite shape.

-Particles move faster than in solids​

Examples: water, gatorade, soda​

​Liquids take the shape of whatever container they are in.

​Liquids have two main properties:

​

Surface tension-holds water together in droplets

​

​

​

​

Viscosity-the resistance to flow​

​ Gases

-Matter that has indefinite shape and indefinite volume.

-Particles move very fast​

Examples: air, helium, oxygen

​

​ Plasma

A gas-like state of matter where atoms have been stripped of electrons.

​

​

​

Examples: fire and lighting

90% of all matter in the universe is plasma​
