What is conduction?

Back

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

What is convection?

Back

Convection is the transfer of heat through a fluid (liquid or gas) caused by the movement of the fluid itself. Warmer parts of the fluid rise while cooler parts sink, creating a circulation pattern.

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 and can occur in a vacuum.

Front

Give an example of conduction.

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

Give an example of convection.

Back

An example of convection is warm air rising and cool air sinking in a room, creating a circulation of air.

Front

Give an example of radiation.

Back

An example of radiation is feeling the warmth of the sun on your skin, even when you are not in direct contact with it.

Front

What materials are good conductors of heat?

Back

Metals like copper and aluminum are good conductors of heat.

Front

What materials are good insulators?

Back

Materials like wood, plastic, and rubber are good insulators, meaning they do not conduct heat well.

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere can lead to the formation of clouds and storms, as warm air rises and cool air sinks.

Front

What role does radiation play in heating the Earth?

Back

Radiation from the sun heats the Earth's surface, which then warms the air above it.
