Conduction, Convection, & Radiation

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

Convection is the transfer of heat through liquids and gases, where warmer, less dense areas rise and cooler, denser areas sink, creating a circulation pattern.

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 heat transfer occur between two objects at different temperatures?

Back

Heat transfers from the warmer object to the cooler object until thermal equilibrium is reached.

Front

What happens to thermal energy when two objects are in contact?

Back

Thermal energy passes from the warmer object to the cooler object.

Front

What is the primary way heat travels through solids?

Back

Conduction is the primary way heat travels through solids.

Front

What is an example of radiation?

Back

A car’s inside temperature rises to over 100 degrees on a sunny day due to radiation from the sun.

Front

What is an example of convection?

Back

Boiling water in a pot, where hot water rises and cooler water sinks, creating a circulation.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.

Front

What is the difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in liquids and gases through the movement of the fluid.
