___________________ this state of matter has a definite shape and definite volume (they don't change).
solid
liquid
gas
matter
This state of matter takes both the shape and volume of it container (spreads out).
gas
solid
liquid
When boiling water creates steam (a gas).
condensation
melting
freezing
vaporization
When dripping water turns into solid icicles.
melting
freezing
vaporization
condensation
Particles of a liquid
are tightly packed together and stay in a fixed position.
Spread really far apart
are free to move around one another but still touch.
