Presentation transcript:

Do Now What are the main 3 states of matter? Can you name the other 2 states of matter? Describe the shape and volume of particles in a solid. Describe the shape and volume of a gas. Solid, Liquid, Gas Plasma, Bose-Einstein Condensate Definite Shape, Definite Volume Indefinite Shape, Indefinite Volume

The five states of matter: PLASMAS (only for low density ionized gases) BOSE-EINSTEIN CONDENSATE SOLIDS LIQUIDS GASES Thermal Energy Lower Temperature Higher Temperature

Changing States of Matter Draw the chart in your notes!! Melt Vaporization Gas Solid Liquid + heat + heat - heat - heat Freeze condensation

Changes: Solid and Liquid Melting: Solid → Liquid Melting point: Temperature When melting occurs Big Idea: When a substance melts, the particles in the solid vibrate so fast that they break free from their fixed positions. + Thermal Energy →

Changes between Liquid and Solid Freezing: Liquid → Solid Freezing point: Temperature When freezing occurs Big Idea: When a substance freezes, the particles in the liquid move so slowly that they begin to take on a fixed positions. - Thermal Energy →

Pop Quiz True True of False Melting and freezing are reversible physical changes of matter. True

Changes: Liquid and Gas Vaporization: Liquid → Gas. Takes place only on the surface of the liquid. Boiling: Liquid → Gas. Occurs when liquid changes to gas below the surface of the liquid as well as at the surface. Boiling Point: Temperature at which liquid boils. + Thermal Energy →

Changes between Liquid and Gas Condensation: Gas → Liquid. Big Idea: During condensation, the particles loose enough thermal energy to form a liquid. - Thermal Energy →

Changes between Solid and Gas Sublimation: Solid → Gas. During Sublimation, particles of a solid do not pass through the liquid state as they form a gas. When dry ice becomes gas, it cools water vapor in the nearby air. The water vapor then condenses into a liquid, forming fog around the dry ice. + Thermal Energy →
