Heat Transfer

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air rises while cool air sinks, creating a cycle.

How does heat transfer occur when holding hands with someone?

Back

Heat energy from your friend's hand transfers to your hand through conduction, warming your cold hand.

Front

What is radiation in terms of heat transfer?

Back

Radiation is the transfer of heat through waves, such as infrared radiation from the sun.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is an example of convection in everyday life?

Back

An example of convection is boiling water, where hot water rises to the top and cooler water sinks.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is an example of radiation?

Back

An example of radiation is feeling warmth from a campfire without touching it.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises.

Front

What is the role of density in convection?

Back

Density differences in fluids cause warmer, less dense fluid to rise and cooler, denser fluid to sink.

Front

How does heat transfer affect weather patterns?

Back

Heat transfer through convection in the atmosphere can create wind and influence weather patterns.
