science lesson 2

• matter is anything that has mass and volume
• mass is a measure of how much matter is in a substance
• volume is a measure of how much space a substance takes uo
• particles are small pieces of matter we cant see
• particle theory of matter is a simple way of describing matter and its behavior
• 1st main point is all matter is made up of tiny particles
• 2nd main point is that all particles are in constant motion
• 3rd main point is that all particles of one substance are identical
• 4th main point is that temperature affects the speed that particles move in
• 6th main point is that there are spaces between particles
• evaporation is liquid to gas
• condensation is gas to liquid
• freezing is liquid to solid
• melting is solid to liquid
• sublimation is solid to gas
• deposition is gas to solid
