Thermal Energy Transfer Review

Front

What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat energy through electromagnetic waves, such as light, without the need for a medium.

Front

How do warm molecules behave compared to cool molecules?

Back

At warm temperatures, molecules move around more quickly and have more energy than at cool temperatures.

Front

What is an example of conduction?

Back

Burning your hand on a hot pan is an example of conduction.

Front

What is an example of convection?

Back

Boiling water is an example of convection, where hot water rises and cool water sinks.

Front

What is an example of radiation?

Back

The heat from the sun reaching the Earth is an example of radiation.

Front

What happens to molecules when they are heated?

Back

When molecules are heated, they gain energy and move faster.

What is the primary method of heat transfer in solids?

Back

Conduction is the primary method of heat transfer in solids.

What is the primary method of heat transfer in fluids?

Back

Convection is the primary method of heat transfer in fluids.
