Methods of Heat Transfer

Front

What is the method of heat transfer that occurs through the movement of currents within a fluid?

Back

Convection

Front

What is the process called when heat is transferred through direct contact between materials?

Back

Conduction

Front

What is the method of heat transfer that does not require a medium and can occur in a vacuum?

Back

Radiation

Front

Give an example of conduction in everyday life.

Back

A metal pot touching a burner.

Front

What happens to warm air in a room when a ceiling fan is used?

Back

The fan forces the warm air downward, demonstrating convection.

Front

Why do your feet feel cold in the ocean while your arms feel warm?

Back

This is due to convection; the water is cooler than the air.

What is an example of radiation in everyday life?

Back

The warmth felt from the sun on your skin.

Front

How does conduction occur in a metal rod that is heated at one end?

Back

Heat travels through the rod from the hot end to the cooler end by direct contact of particles.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection involves the movement of fluids.
