1819 Thermal Energy Review

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself. It occurs when two objects at different temperatures are in direct contact.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself. Warmer parts of the fluid rise while cooler parts sink, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation. It does not require a medium to travel through, allowing heat to be transferred through empty space.

Front

Give an example of conduction in everyday life.

Back

An example of conduction is when you touch a hot stove and feel the heat transfer to your hand.

Front

Give an example of convection in everyday life.

Back

An example of convection is the way warm air rises and cool air sinks in a room, creating a circulation of air.

Front

Give an example of radiation in everyday life.

Back

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

Front

What type of heat transfer occurs when you walk on warm sand?

Back

Conduction occurs when you walk on warm sand, as heat is transferred from the sand to your feet.

Front

What type of heat transfer occurs in the atmosphere?

Back

Convection is responsible for the circulation of air in the atmosphere.

Front

How does heat transfer from a hot burner to a pot?

Back

Heat is transferred from a hot burner to a pot by conduction.

Front

What is the primary method of heat transfer from the sun to the Earth?

Back

The primary method of heat transfer from the sun to the Earth is radiation.
