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 fluids (liquids and gases) where warmer areas of a liquid or gas rise and cooler areas sink, creating a current.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum, such as heat from the sun.

Front

Example of conduction in everyday life?

Back

Cooking food on a stove using a pan.

Front

Example of convection in everyday life?

Back

Heating water in a pot where the hot water rises and cooler water sinks.

Front

Example of radiation in everyday life?

Back

Feeling warmth from the sun or a fire without direct contact.

Front

Which method of heat transfer is used in a microwave?

Back

Radiation.

Front

Which method of heat transfer is primarily used in an oven?

Back

Convection.

Front

What happens to particles during conduction?

Back

Particles vibrate and transfer energy to neighboring particles through direct contact.

Front

What happens to particles during convection?

Back

Particles in a fluid gain energy, become less dense, and rise, while cooler, denser particles sink.
