Radiation, convection, conduction

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials, typically solids.

Front

What is convection?

Back

Convection is the transfer of thermal energy through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, such as sunlight.

Front

Which materials are good conductors of heat?

Back

Good conductors of heat include metals like copper, aluminum, and iron.

Front

What is an insulator?

Back

An insulator is a material that does not conduct heat well, such as plastic, wood, or rubber.

Front

How does heat transfer from the sun to the Earth?

Back

Heat from the sun reaches the Earth through radiation.

Front

What happens to the temperature of a spoon when placed in hot soup?

Back

The spoon conducts heat from the hot soup, increasing its temperature.

Front

What is an example of convection in everyday life?

Back

An example of convection is the warm air rising and cool air sinking in a room, creating a circulation of air.

Front

How does convection work in boiling water?

Back

In boiling water, hot water rises to the top while cooler water sinks, creating a circular motion.

Front

What is the main difference between conduction and convection?

Back

Conduction occurs in solids through direct contact, while convection occurs in fluids through movement.
