Science Chapter 2 Vocab

Question 0

Crystalline Solid

Answer 0

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

Question 1

Solid

Answer 1

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

Question 2

Amorphous Solids

Answer 2

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

Question 3

Liquid

Answer 3

A state of matter that has no definite shape but has a definite volume.

Question 4

Liquid

Answer 4

Any substance that can flow

Question 5

Surface Tension

Answer 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

Question 6

Viscosity

Answer 6

A liquid’s resistance to flowing.

Question 7

Gas

Answer 7

A state of matter with no definite shape or volume

Question 8

Pressure

Answer 8

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

Question 9

Melting

Answer 9

The change in state from a solid to a liquid

Question 10

Melting Point

Answer 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.

Question 11

Freezing

Answer 11

The change in state from a liquid to a solid.

Question 12

Vaporization

Answer 12

The change of state from a liquid to a gas.

Question 13

Evaporation

Answer 13

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

Question 14

Boiling

Answer 14

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

Question 15

Boiling Point

Answer 15

The temperature at which a liquid boils

Question 16

Condensation

Answer 16

The change in state from a gas to a liquid.

Question 17

Sublimation

Answer 17

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

Question 18

Charles’s Law

Answer 18

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

Question 19

Directly Proportional

Answer 19

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

Question 20

Boyle’s Law

Answer 20

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

Question 21

Inversely Proportional

Answer 21

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