States of Matter SWBAT describe the states of matter on earth; explain the reasons that matter exists in these states; relate the role of thermal energy to changes of state of matter

Solids Substances with densely packed particles arranged in a definite pattern Substances with densely packed particles arranged in a definite pattern Has both definite shape and volume Has both definite shape and volume Crystaline structures Crystaline structures Particles are arranged in regular geometric patterns Particles are arranged in regular geometric patterns Create flat faces and straight edges between faces Create flat faces and straight edges between faces Sublimation Sublimation Change of solid into a gas, without the intermediate liquid stage Change of solid into a gas, without the intermediate liquid stage
Liquids Particles are able to slide past one another Particles are able to slide past one another Have no definite shape, but have a definite volume Have no definite shape, but have a definite volume Melting point Melting point When the particles in a solid move fast enough (caused due to rising temperature) to break apart When the particles in a solid move fast enough (caused due to rising temperature) to break apart Evaporation Evaporation When a liquid changes to a gas When a liquid changes to a gas
Gases Particles are separated by large distances and move about at extremely high speeds Particles are separated by large distances and move about at extremely high speeds Have no definite shape or volume Have no definite shape or volume Boiling point Boiling point When liquids heat to the point where the particles escape the liquid When liquids heat to the point where the particles escape the liquid Condensation Condensation When gases are cooled enough to change to a liquid When gases are cooled enough to change to a liquid
