Conduction, Convection, and Radiation Flashcard

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when molecules collide and transfer energy to neighboring molecules.

Example of conduction in everyday life?

Back

Ironing a shirt is an example of conduction, where the heat from the iron is transferred directly to the fabric.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). It occurs when warmer, less dense areas of a fluid rise and cooler, denser areas sink.

Example of convection in everyday life?

Back

Moving water in a pot of boiling water is an example of convection, where hot water rises and cooler water sinks.

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.

Example of radiation in everyday life?

Back

A microwave cooking food is an example of radiation, where microwaves heat the food directly.

Front

How does an electric blanket warm you?

Back

An electric blanket warms you through conduction, as it transfers heat directly to your body.

Front

What happens to warm air from a fireplace?

Back

Warm air from a fireplace rises due to convection, creating a circulation of air in the room.

Front

What is the role of density in convection?

Back

Density plays a crucial role in convection; warmer fluids are less dense and rise, while cooler fluids are denser and sink.

Front

How does conduction differ from convection?

Back

Conduction requires direct contact for heat transfer, while convection involves the movement of fluids.
