essay write - up: what did you learn about the states of matter: describe.

Explanation:

1. Volume is the measure of the space occupied by an object, so it matches d.
2. Mass is the amount of matter that an object contains, so it matches i.
3. A substance is matter that has a uniform and definite composition, so it matches c.
4. A physical property is a quality or condition of a substance that can be observed or measured without changing the substance’s composition, so it matches a.
5. A solid is matter that has a definite shape and volume, so it matches h.
6. A liquid is matter that has a definite volume and takes the shape of its container, so it matches e.
7. A gas is matter that takes both the shape and volume of its container, so it matches b.
8. Vapor is the gaseous state of a substance that generally exists as a liquid or solid at room - temperature, so it matches g.
9. A physical change is a change to a material that does not change its composition, so it matches f.
10. An extensive property depends on the amount of matter in a sample, so it matches k.
11. An intensive property depends on the type of matter in a sample, so it matches j.

26.
a. Steam is vapor. Explanation: Steam is the gaseous state of water which is a liquid at room - temperature.
b. Apple juice is a liquid. Explanation: It has a definite volume and takes the shape of its container.
c. Gasoline is a liquid. Explanation: It has a definite volume and conforms to the shape of its container.
d. Hockey puck is a solid. Explanation: It has a definite shape and volume.
e. Air is a gas. Explanation: It takes the shape and volume of its container.

27.
a. Melting butter is a physical change. Explanation: The composition of butter does not change, only its state from solid to liquid.
b. Breaking a window is a physical change. Explanation: The glass remains glass, only its shape is changed.
c. Burning gasoline is not a physical change. Explanation: Gasoline reacts with oxygen to form new substances like carbon dioxide and water, so its composition changes.
d. Boiling water is a physical change. Explanation: The water changes from liquid to gas, but its chemical composition (H₂O) remains the same.
