Front 1

Temperature

Back 1

The measure of the average kinetic energy of the particles in matter.

Front 2

Fahrenheit Scale

Back 2

The temperature scale on which water freezes at 32 degrees and boils at 212 degrees.

Front 3

Celsius Scale

Back 3

The temperature scale on which water freezes at 0 degrees and boils at 100 degrees.

Front 4

Kelvin Scale

Back 4

The temperature scale on which zero is the temperature at which no more energy can be removed from matter.

Front 5

Absolute Zero

Back 5

The temperature at which no more energy can be removed from matter.

Front 6

Heat

Back 6

Thermal energy that is transferred from matter at a higher temperature to matter at a lower temperature.

Front 7

Specific Heat

Back 7

The amount of heat required to raise the temperature of 1 kilogram of a material by 1 Kelvin.

Front 8

Conduction

Back 8

The transfer of heat from one particle of matter to another.

Front 9

Convection

Back 9

The transfer of heat by the movement of currents within a fluid.

Front 10

Convection Current

Back 10

A current caused by the rising of heated fluid and sinking of cooled fluid.

Front 11

Radiation

Back 11

The transfer of energy by electromagnetic waves.

Front 12

Conductor

Back 12

A material that conducts heat well.

Front 13

Insulator

Back 13

A material that does not conduct heat well.

Front 14

State

Back 14

One of 3 forms of matter--solid, liquid, gas--in which most matter on Earth exists.

Front 15

Change of State

Back 15

The physical change of matter from one state to another.

Front 16

Melting

Back 16

The change from solid to liquid state of matter.

Front 17

Freezing

Back 17

The change from the liquid to the solid state of matter.

Evaporation

Back 18

Vaporization that occurs at the surface of a liquid

Front 19

Boiling

Back 19

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

Front 20

Condensation

Back 20

The change from the gaseous to the liquid state of matter

Front 21

Thermal Expansion

Back 21

The expansion of matter when it is heated.

Front 22

Heat Engine

Back 22

A device that converts thermal energy into mechanical energy.

Front 23

External Combustion Engine

Back 23

An engine powered by fuel burned outside the engine.

Front 24

Internal Combustion Engine

Back 24

An engine that burns fuel inside cylinders within the engine.

Front 25

Refrigerant

Back 25

The substance that absorbs and releases heat in a cooling system.
