Heat Transfer Flashcardizz

Front

What is convection?

Back

Convection is the type of heat transfer that occurs in fluids (liquids and gases) where warmer, less dense areas rise and cooler, denser areas sink, creating a circulation pattern.

How does convection keep a hot air balloon in the air?

Back

The heat is rising and circulating, causing the balloon to stay up in the air.

Front

What is conduction?

Back

Conduction is the type of heat transfer that happens through direct contact of molecules or particles with each other.

Front

Give an example of conduction.

Back

An egg cooking in a frying pan is a good example of conduction.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight warming the Earth.

Front

How does the sun's heat reach the Earth?

Back

The sun's heat reaches the Earth through radiation.

Front

What is the primary method of heat transfer in fluids?

Back

Convection is the primary method of heat transfer in fluids.

Front

What happens to air when it is heated?

Back

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

Front

What is an example of convection in nature?

Back

Wind is an example of convection, as warm air rises and cool air sinks.

Front

What is the difference between conduction and convection?

Back

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