states of matter
Solid
Liquid
Gas - ✔✔ correct answer Solid- Definite shape, definite volume, particules are in a fixed position,
close to one another, vibrate in place, and move slowely.
Liquids- Indefinate shape, definite volume, in a fixed position, and able to "flow" around each other.
Gas- Indefinite shape, indefinite volume, Not in a fixed position, and they move freely and
randomely.
Define physical property and give an example. - ✔✔ correct answer Can be observed or measured
without changing the composition of matter. Ex: Elasticity
Define chemical property and give an example. - ✔✔ correct answer Indicates how a substance
reacts with something else. Ex: Ability for iron to rust.
Define physical change and give an example. - ✔✔ correct answer Change in which the identity of
the substance does not change. Ex: Water becoming ice.
Define chemical change and give an example. - ✔✔ correct answer A new substance is produced.
The new change cannot be undone. Ex: Iron being exposed to air.
Define substance. - ✔✔ correct answer A type of matter with fixed position.
Define compound. - ✔✔ correct answer Two or more elements combine to form substances.
What are examples of pure substances? - ✔✔ correct answer Water, gasoline, sugar.
