Properties of Matter

Question 1

Physical Properties & Examples

Answer 1

observations of a substance without changing it into another substance;
boiling point, density, mass, volume

Question 2

Chemical Properties & Examples

Answer 2

observations only when a substance is changed into another substance; flammability, corrosiveness, reactivity with acid

Question 3

Are extensive and intensive properties physical or chemical properties?

Answer 3

physical properties

Question 4

Extensive properties & Examples

Answer 4

properties that depend on the amount of matter in a sample; mass, length, volume, energy

Question 5

Intensive properties & Examples

Answer 5

properties that don’t change regardless of if the amount of matter changes; density, color, temperature

Question 6

A substance changes its physical appearance, not its composition. It’s the same substance before and after.

Answer 6

physical change

Question 7

A substance becomes a chemically different substance

Answer 7

chemical change/chemical reaction

Question 8

Examples of physical/chemical changes

Answer 8

changes of state, temperature, volume; combustion, oxidation, decomposition

Question 9

Converting between the three states of matter is a chemical change. True or False?

Answer 9

False

Question 10

Example of chemical reaction

Answer 10

hydrogen & oxygen become water

Question 11

Filtration, distillation, & chromatography serve what purpose?

Answer 11

separate mixtures

Question 12

Filtration

Answer 12

solids are separated from liquids & solutions

Question 13

Distillation

Answer 13

separate homogeneous mixtures based on the differences in boiling points

Question 14

Chromatography

Answer 14

separates substances based on the ability to stick to a solid surface
