Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when heat moves from a hotter object to a cooler one through physical touch.

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 fluid rises and cooler, denser fluid sinks, creating a circulation pattern.

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

Example of conduction in everyday life?

Back

Touching a hot stove and feeling the heat transfer to your hand.

Front

Example of convection in everyday life?

Back

Boiling water in a kettle where hot water rises and cooler water sinks.

Front

Example of radiation in everyday life?

Back

Feeling the warmth of the sun on your skin.

Front

What happens to a car's temperature on a sunny day due to radiation?

Back

A car’s inside temperature rises to over 100 degrees due to the heat from the sun being absorbed.

Front

How does heat transfer when you touch hot sand?

Back

Heat is transferred by conduction to your skin when you touch hot sand.

Front

What is the primary method of heat transfer in liquids?

Back

Convection is the primary method of heat transfer in liquids.

Front

What is the primary method of heat transfer in solids?

Back

Conduction is the primary method of heat transfer in solids.
