Heat Transfer Task Cards

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 parts of the fluid rise while cooler parts sink.

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, allowing heat to be transferred through empty space.

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 of heat?

Back

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

Front

How does temperature affect conduction?

Back

Higher temperatures increase the energy of particles, leading to faster conduction as particles collide more frequently.

Front

How does temperature affect convection?

Back

In convection, warmer fluids are less dense and rise, while cooler fluids are denser and sink, creating a cycle.
