What’s Matter?
Matter is anything that has mass and takes up space
Particle Theory Of Matter
All matter is made up of tiny particles that have spaces between them
Different substances are made up of different atoms
Particles are attracted to each other
Particles are in constant motion
As the temperature increases the particles move faster
What is this state of matter and its particles behavior?
Solid- They are held firmly in place but can vibrate within a limited area
What is this state of matter and its particles behavior?
Liquid- Flow easily around one another, they are kept from flying apart by attracted forces between them, and shape their containers
What is this state of matter and its particles behavior?
Gas - Fly in all directions at great speeds they are so apart that attractive forces between them are insignificant.
