Phases of Matter  Matter is anything that has mass and takes up space  Matter is the material that makes up all the things in the universe Except for forms of energy like heat, light, and sound Except for forms of energy like heat, light, and sound Energy is not something made of matter; it is the ability to get work done Energy is not something made of matter; it is the ability to get work done  All matter is made up of tiny particles called atoms  There are 3 states or phases in which matter exists: Solids Solids Liquids Liquids Gases Gases  Water takes one of the 3 phases throughout the water cycle: Solid - ice, snow, hail, sleet Solid - ice, snow, hail, sleet Liquid - rain, run-off, ground water, ponds, reservoirs Liquid - rain, run-off, ground water, ponds, reservoirs Gas - water vapor in the air from evaporation and transpiration, steam Gas - water vapor in the air from evaporation and transpiration, steam

Solids  Most objects around you are solids  A solid is a phase of matter that has a definite shape and a definite volume Volume is the amount of space an object takes up Volume is the amount of space an object takes up  Solid particles are tightly packed together  Particles cannot change position easily  Particles can only vibrate back and forth  Examples: ice cubes, desks, chairs, pens

Liquids  A liquid is a phase of matter that has a definite volume, but no definite shape  Liquids can change shape because their particles glide past one another (like ice- skaters)  A liquid will take the shape of its container  The volume will remain the same  Examples: water you pour into a glass, milk, fruit punch, melted chocolate

Gases  A gas is a phase of matter that has no definite shape and no definite volume  Gases take the shape of whatever they are put into  Think of air inside a balloon, a bicycle tire, or in a football  Particles move freely to all parts of a container therefore having no definite shape or volume  Examples: air, oxygen, carbon dioxide, helium, nitrogen, water vapor (steam)
