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. Hot fluid rises while cooler fluid sinks, creating a circulation pattern.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, which is why we can feel the heat from the sun.

Front

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

Example of convection in everyday life?

Back

An example of convection is boiling water in a pot; the hot water rises to the top while cooler water sinks.

Example of radiation in everyday life?

Back

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

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 of heat?

Back

Materials like wood, plastic, and rubber are good insulators of heat.

Front

How does convection affect weather patterns?

Back

Convection currents in the atmosphere can lead to the formation of clouds and storms.

Front

What is the role of radiation in heating the Earth?

Back

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