Heat Transfer and Christmas

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three main methods of heat transfer?

Back

Conduction, convection, and radiation.

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) caused by temperature differences.

Front

What is radiation?

Back

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

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster; as temperature decreases, particles move slower.

Front

What happens to the temperature of a substance when its particles move more slowly?

Back

The temperature decreases.

Front

In heat transfer, heat always flows from which substance to which substance?

Back

Heat always flows from the hotter substance to the colder substance.

Front

What is a good insulator of heat?

Back

Wood is a good insulator of heat.

Front

What is an example of heat transfer through convection?

Back

Boiling water in a pot is an example of heat transfer through convection.
