Page 4R States of Matter

Remember…the basic particle is an ATOM Atoms are amazing! They are the smallest particle known to exist. BUT – how these tiny particles move totally affects the structure of matter! When there is change in matter it is a PHYSCIAL CHANGE 4

1st state of matter: Solid Particles Arrangement- tightly packed Particle Motion- vibrate Energy- Slow Volume- Definite (fixed) Shape-Definite (fixed) Density-High except for water (it has medium density) Structure- crystalline

2nd State of Matter: Liquid Particles Arrangement- close Particle Motion- slide past one another Energy- Medium Volume- Definite Shape- Indefinite Density-Medium except for water (it has high density)

3rd State of Matter: Gas Particles Arrangement- Far apart Particle Motion- fast and move in all directions Energy- High Volume- Indefinite Shape- Indefinite Density- Low

Stand Up and Show the states of matter Solid- Stand 1 foot away from your classmates and shake Liquid- Slide slowly past one another, but don’t get too far away Gas- WALK past one another, move in all directions
