state of matter

science

Molecules

Two or more atoms bonded together

Matter

Anything that has weight and takes up space

Thermal Energy

Heat

States of Matter

“Ways” matter can be found–solid, liquid, gas, and plasma

Solid

State of matter where molecules are very tightly packed together Has definite shape AND definite volume. Molecules vibrate

Liquid

State of matter where molecules are close together, but can move around each other.  Has an indefinite shape (takes the shape of its container), but a definite volume

Gas

State of matter where molecules are far apart and moving quickly. Has an indefinite shape and an indefinite volume Spreads out

Plasma

State of matter similar to gas,but the molecules have a charge

Vaporization

Phase change when matter moves from a liquid to a gas (heat energy increases)

Condensation

Phase change when matter moves from a gas to a liquid (heat energy decreases)

Deposition

Phase change when matter moves from a gas to a solid and skips the liquid state (heat energy decreases)

Freezing

Phase change when matter moves from a liquid to a solid (heat energy decreases)

Melting

Phase change when matter moves from a solid to a liquid (heat energy increases)

Sublimation

Phase change when matter moves from a solid to a gas and skips the liquid state (heat energy increases)
