Motion and design List 3
engineer-trained person who designs or builds
mass-amount of matter in an object
physical change-alteration in the form, but not in the material
chemical change-process that alters form and composition
solid-state of matter that has definite shape
liquid-a substance that flows, a fluid
gas-invisible state of matter, like air
vapor-small particles of moisture in the air
matter-is anything that has a mass and a volume (the amount of space it takes up). It is made up of atoms or molecules
physical property-is something you can see or observe about matter without having to change the kind of matter it is.
Law of Conservation - A law that states that matter cannot be created or destroyed by ordinary means BUT it can certainly be changed.
Heat-If something is hot, it will move faster than something that is cold.

- Fast Molecules = Heat
- Slow Molecules = Cold
