2. Solid- phase in which
matter has a definite shape
and volume.
3. Liquid- matter with no
definite shape, but with a
definite volume.
4. Plasma- phase in which

contained by ordinary
matter, very rare on Earth.
5. Crystal- a solid in
which the particles are
arranged in a regular,
repeating pattern.
6. Boiling- process in
which particles inside a

phase.
14. Vaporization- change of a
liquid to a gas.
15. Sublimation- change from
