1. a characteristic of matter that allows it to change to something new is a

a) physical change b) chemical change
c) chemical property d) physical property

1. the following are examples of chemical properties except

a) ability to burn b) ability to be crushed
c) toxicity d) ability to react with oxygen
3.
a) flammability b) density
c) combustibility d) oxidation

1. density depends on

a) volume b) weight
c) mass d) mass and volume

1. you can separate sugar from sand because sugar is

a) soluble in water b) ductile
c) malleable d) acidic

1. an example of a chemical property is

a) ability to be attracted by a magnet b) ability to react with oxygen
c) boiling point d) solubility

1. which of the following is not a physical property of matter

a) density b) melting point
c) flammability d) solubility

Explanation:

1. A chemical property allows matter to change into something new.
2. The ability to be crushed is a physical property, not a chemical one. Chemical properties involve chemical reactions.
3. Density is a physical property that describes the mass - to - volume ratio of a substance.
4. Density is calculated as $

ho=\frac{m}{V}$, so it depends on mass and volume.

1. Sugar is soluble in water while sand is not, which enables separation.
2. Reacting with oxygen is a chemical property as it involves a chemical reaction.
3. Flammability is a chemical property as it involves a substance burning (a chemical reaction), while density, melting point, and solubility are physical properties.

Answer:

1. c) chemical property
2. b) ability to be crushed
3. b) density
4. d) mass and volume
5. a) soluble in water
6. b) ability to react with oxygen
7. c) flammability
