Radiation, convection, conduction

Front

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.

Front

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, less dense fluid rises while cooler, denser fluid sinks.

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.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well. It slows down the transfer of heat.

Front

What is a conductor?

Back

A conductor is a material that allows heat to pass through it easily. Metals like copper and aluminum are good conductors.

Front

How does heat move between objects?

Back

Heat moves from warmer objects to cooler objects until they reach the same temperature.

Front

What happens when hot and cold water are mixed?

Back

Heat (thermal) energy from the hot water is transferred to the cold water, causing them to reach the same temperature.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is when a metal spoon gets hot after being placed in a pot of hot soup.

Front

What is 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

What is an example of radiation in everyday life?

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.
