2.) is a measure of the mass of an object in a given volume.

3.)A(n) is easily observed or measured without changing the object.

4.) result in a new substance and cannot be reversed by physical means.

2. Density

3. Physical Property

4. Chemical Change

5. states of matter

Explanation: Density is referred as mass per unit volume. Physical properties are observable characteristics of an object. An new formation of a substance in a chemical reaction is a chemical change. And solids, liquids, and gases are states of matter.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
