Topic 4: Thermal Energy

Front

What does the Law of Conservation of Energy state?

Back

Energy is never created or destroyed, it is only transformed.

Front

What is conduction?

Back

Conduction is the transfer of energy from one particle of matter to another that are in direct contact.

Front

What method of heat transfer caused Emerson to burn herself when picking up a hot iron pot?

Back

Conduction.

Front

How were Sadie's hands warmed when she used a hand warmer?

Back

Heat was transferred by conduction, resulting in an increase in energy.

Front

What method of heat transfer was observed when the water in the pot started to boil?

Back

Convection.

Front

Define convection.

Back

Convection is a type of heat transfer that occurs through the movement of fluids or gases.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of energy by electromagnetic waves.

Front

Give an example of conduction in everyday life.

Back

Touching a hot stove and getting burned.

Front

What is the primary method of heat transfer in liquids and gases?

Back

Convection.

Front

How does a thermos keep drinks hot or cold?

Back

By minimizing heat transfer through conduction, convection, and radiation.
