choose the correct answer for each question.

1. which of the following is a physical property?

a. flammability
b. reactivity
c. density
d. toxicity

1. which property is not intensive?

a. color
b. density
c. texture
d. mass

1. what type of property is the boiling point of water?

a. chemical
b. physical
c. extensive
d. both b and c

1. which of the following describes a chemical property?

a. melting point
b. ductility
c. flammability
d. transparency

1. if you cut a piece of metal in half, which property remains the same?

a. mass
b. volume
c. density
d. length

1. the ability of a substance to allow heat to flow through it is called:

a. malleability
b. conductivity
c. reactivity
d. toxicity

1. which of the following is an extensive property?

a. density
b. color
c. texture
d. volume

1. what is a property that does not depend on the amount of substance present?

a. intensive
b. extensive
c. chemical
d. flammable

Explanation:

1. Intensive properties don't depend on amount; density fits this.
2. Intensive properties don't depend on sample size; mass depends on amount.
3. Boiling point is a physical property (no new substance forms).
4. Flammability involves a chemical reaction (burning), so it's a chemical property.
5. Density is an intensive property, so it doesn't change with sample size.
6. Conductivity is the ability of a substance to transfer heat/electricity.
7. Extensive properties depend on the amount of substance; volume fits this.
8. Intensive properties are independent of the amount of substance present.

Answer:

1. B. Density
2. D. Mass
3. B. Physical
4. C. Flammability
5. C. Density
6. B. Conductivity
7. D. Volume
8. A. Intensive
