Liquids The state of matter in which a substance exhibits a characteristic readiness to flow, little or no tendency to disperse, and relatively high incompressibility. Matter or a specific body of matter in this state. Matter is everything around you. On Earth, matter is usually found in one of three states, or phases. The three main states of matter are solid, liquid, and gas.

Solids A substance having a definite shape and volume; one that is neither liquid nor gaseous.

Gases a substance possessing perfect molecular mobility and the property of indefinite expansion, as opposed to a solid or liquid.

Comparisons Gas Particles * Gas are well separated with no regular arrangement. * Gas vibrate and move freely at high speeds.

Comparisons Liquid Particles * Liquid are close together with no regular arrangement. * Liquid vibrate, move about, and slide past each other.

Comparisons Solid Particles * Solid are tightly packed, usually in a regular pattern. * Solid vibrate (jiggle) but generally do not move from place to place.

Physical Changes Physical changes occur when objects undergo a change that does not change their chemical nature. A physical change involves a change in physical properties. Physical properties can be observed without changing the type of matter. Examples of physical properties include: texture, shape, size, color, odor, volume, mass, weight, and density.

Physical Changes Elements move from one phase to another when physical forces are present * Examples: solid to a liquid liquid to gas

Physical Changes Increased temperature/Increased Pressure Decreased temperature/Decreased Pressure

Temperature Temperature changes materials from one state of matter to another.  Heated solids melt into liquids. Heated liquids evaporate into gases.  Cooled gases condense into liquids. Cooled liquids freeze into solids.
