Energy And Heat 2

Front 1

An objects stored energy is called

Back 1

potential energy

Front 2

Sunlight can be turned into electricity by using

Back 2

solar cells to collect the sun's energy.

Front 3

If two pots of boiling water are exactly the same size and are at exactly the same temperature, the ____ energy of each is the ____ .

Back 3

Heat same

Front 4

The graph of the relationship between the temperature of a substance and its amount of heat (amount of particle movement) is

Back 4

a diagonal line that slants upward

Front 5

Three logs in a fire place are lit and begin to burn. This is an example of

Back 5

Transfer of chemical energy to heat and light energy

Front 6

Fourth of July fireworks explode in the air. This is an example of

Back 6

Transfer from chemical energy to light, sound, and heat energy.

Front 7

The amount of heat energy of a liquid depends on the

Back 7

temperature of the liquid and the amount of liquid present.

Front 8

In a phase change diagram, the solid state is represented by a

Back 8

diagonal at the left side of the graph.

Front 9

In a phase change diagram, the horizontal lines in the graph represent

Back 9

the temperature at which the phase change occurs.

Front 10

Theoretically, absolute energy cannot be reached because heat energy is always transferred when

Back 10

objects come into contact.

Front 11

A substance that reduces the flow of heat energy is called an

Back 11

insulator.

Front 12

When thermal energy is transferred from one solid to another by direct contact, the process is called

Back 12

conduction.
