2. a. A _solid_ is the first state of matter.
i. Solids have a definite _shape_ and _volume_.
The particles that make up a solid are tightly _packed_ and _stay_ in one position.
iii. The particles are not sitting still but _vibrating_ in place.

3. B. Types of Solids
i. _Crystalline_ _structures_ are formed when particles for a repeated pattern.
ii. When a crystalline structure is heated it _melts_ at a specific temperature.
iii. _Amorphous_ _solids_ are solids where its particles are not arranged in a regular pattern.
iv. Amorphous solids do not have a distinct _melting_ _point_. They instead soften or _change_ to another substance.

4. a. A _liquid_ is the second state of matter.
i. Liquids have a definite _volume_ but no _shape_ of their own.
ii. Particles in a liquid are _tightly_ packed but are able to _move_ _freely_.
iii. The freely moving particles allows the liquid to _flow_.
iv. _Fluid_ means a substance that flows.

5. b. Properties of a liquid
i. _Surface_ _tension_ is the result of an inward pull among the molecules of a liquid that bring the molecules on the surface closer.
ii. A liquids resistance to flowing is called _viscosity_.
iii. High viscosity causes liquid to flow _slowly_.
iv. Low viscosity causes liquid to flow _quickly_.

6. a. _Gas_ is the third state of matter.
iii. Gases
a. _Gas_ is the third state of matter.
i. Gas has no _volume_ and can change its _shape_.
ii. Gas particles move and _spread_ _apart_ filling up the entire space.
