States of Matter

Solids--definite shape-definite volume-particles (atoms) are tightly packed together-particles are organized in a regular pattern-particles vibrate around a fixed location

Liquids- -not a definite shape, takes the shape of the container-definite volume-atoms are closely packed, but free flowing-atoms are more randomly organized than solids-particles can flow to a new location-force of attraction keeps particles together

States of matter

Gases--not a defiinite shape or volume-loosely packed atoms with more space between-atoms are randomly organized-particles in a constant, random motion-unffected by motion of other particles unless they collide-force of attraction is weak

Freezing- As energy decreases, molecules move more slowly. When all molecules are arranged in an organized pattern, freezing is complete.Condensation- As gas that looses energy when coming into contact with something cooler will turn into a liquid. Molecules slow down and go from random to slightly organized. ex: cold soda bottle forming water dropletsDeposistion- gas changing directly into a solid. It quickly looses enough energy to skip the liquid phase. Molecules slow down and go from random to an organized pattern. ex- frost on ur windshildMelting- Molecules gain energy and vibrate faster. When all molecules gain enough energy to over come attraction and become less organized, melting is complete.Vaporization- The substance must gain enough energy to change from a liquid to a gas. Molecules begin to move faster and become more random. It includes boiling (within the liquid) and evaporation.(at the surface)Sublamation- Changing directly from a solid to a gas. it gains enough energy to skip the liquid phase.
