Heat Transfer

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 types of heat transfer?

Back

The three main types of heat transfer are 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).

Front

What is radiation?

Back

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

Front

How does heat transfer occur in conduction?

Back

Heat transfer in conduction occurs when particles in a material collide and transfer energy to neighboring particles.

Front

Can you give an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

Can you give an example of convection?

Back

An example of convection is warm air rising in a room, creating a circulation pattern.

Front

Can you give an example of radiation?

Back

An example of radiation is feeling warmth from the sun on your skin.

Front

True or False: Heat always flows from cooler objects to warmer objects.

Back

False. Heat flows from warmer objects to cooler objects.
