What is a Solid?* Firm, hard, or

compact* Completely filled up* Able to feel, touch,

and hold

Examples of Solids

* Ice* Snow* Hail

Properties of a Solid

* Holds shape* Fixed volume* Something you can

hold

What is a Liquid?* Composed of free

* Shape depends on container

* Free surface* Fixed volume

Very small part/piece Liquids and solids made up of them Behaviors differ

Microscopic Particles

If a Solid Melts…

* It becomes a liquid* Takes the form of its
