How does heat energy move?

Back

Heat energy moves in three ways: conduction (through direct contact), convection (through fluids), and radiation (through space).

What happens to ice when it is placed under a lamp?

Back

The heat from the lamp causes the ice to absorb energy, which makes it melt faster.

What happens to the temperature of a spoon when it is placed in hot soup?

Back

The temperature of the spoon increases as it absorbs heat from the hot soup.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

What is the direction of heat flow?

Back

Heat flows from warmer objects to cooler objects.
