A state of matter that has a definite shape and a definite volume.

Answer 1

Solid

Question 2

A solid that is made up of crystals in which particles are arranged in a regular, repeating pattern.

Answer 2

Crystalline solid

Question 3

A solid made up of particles that are not arranged in a regular pattern.

Answer 3

Amorphous solid

Question 4

Any substance that can flow.

Answer 4

Fluid

Question 5

The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together; causes the surface to act as if it has a thin skin.

Answer 5

Surface tension

Question 6

A liquid’s resistance to flowing.

Answer 6

Viscosity

Question 7

A state of matter with no definite shape or volume

Answer 7

Gas

Question 8

The force pushing on a surface divided by the area of that surface.

Answer 8

Pressure

Question 9

The change in state from a solid to a liquid.

Answer 9

Melting

Question 10

The temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid changes to a solid.

Answer 10

Melting point

Question 11

The change in state from a liquid to a solid.

Answer 11

Freezing

Question 12

The change of state from a liquid to a gas

Answer 12

Vaporization

Question 13

The process by which molecules at the surface of a liquid absorb enough energy to change to a gas.

Answer 13

Evaporation

Question 14

Vaporization that occurs at and below the surface of a liquid.

Answer 14

Boiling

Question 15

The temperature at which a liquid boils.

Answer 15

Boiling point

Question 16

The change in state from a gas to a liquid.

Answer 16

Condensation

Question 17

The change in state from a solid directly to a gas without passing through the liquid state.

Answer 17

Sublimation

Question 18

A principle that describes the relationship between the temperature and volume of a gas at constant pressure.

Answer 18

Charles law

Question 19

A term used to describe the relationship between two variables whose graph is a straight line passing through the point (0, 0).

Answer 19

Directly proportional

Question 20

A principle that describes the relationship between the pressure and volume of a gas at constant temperature.

Answer 20

Boyle’s law

Question 21

A term used to describe the relationship between two variables whose product is constant.

Answer 21

Inversely proportional
