Q

Crystalline Solid

A

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

1
Q

Solid

A

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

2
Q

Amorphous Solids

A

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

3
Q

Liquid

A

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

4
Q

Liquid

A

Any substance that can flow

5
Q

Surface Tension

A

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

6
Q

Viscosity

A

A liquid’s resistance to flowing.

7
Q

Gas

A

A state of matter with no definite shape or volume

8
Q

Pressure

A

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

9
Q

Melting

A

The change in state from a solid to a liquid

10
Q

Melting Point

A

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.

11
Q

Freezing

A

The change in state from a liquid to a solid.

12
Q

Vaporization

A

The change of state from a liquid to a gas.

13
Q

Evaporation

A

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

14
Q

Boiling

A

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

15
Q

Boiling Point

A

The temperature at which a liquid boils

16
Q

Condensation

A

The change in state from a gas to a liquid.

17
Q

Sublimation

A

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

18
Q

Charles’s Law

A

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

19
Q

Directly Proportional

A

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

20
Q

Boyle’s Law

A

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

21
Q

Inversely Proportional

A

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