Liquid
A _______________ is a form of matter that has an _____________ _________________, flows, yet has a _____________ volume.
The arrangement of particles is different in solids, liquids, and gases. In a liquid, the particles are close together, but they are free to flow past one another.

States of Matter
Gases
A ______________ is a form of matter that takes both the _______________ and _______________ of its container.
The arrangement of particles is different in solids, liquids, and gases. In a gas, the particles are relatively far apart and can move freely. Relating Cause and Effect Use the arrangements of their particles to explain the general shape and volume of solids and gases.

States of Matter
____________ describes the gaseous state of a substance that is generally a _______________ or ________________ at _________________ temperature, as in water vapor.

14. 2.1
Physical Changes
During a _______________ change, some properties of a material change, but the __________________ of the material does not change.
As gallium melts in a person’s hand, the shape of the sample changes, but the composition of the material does not change.
The silvery substance in the photograph is gallium, which has a melting point of 30°C. Inferring What can you infer about the temperature of the hand holding the gallium?

Physical Changes
Physical changes can be classified as _____________ or _________________.
All physical changes that involve a change from one state to another are reversible.
Cutting hair, filing nails, and cracking an egg are examples of irreversible physical changes.
