Convection, Conduction, Radiation Practice

Front

What is conduction?

Back

Conduction is the transfer of thermal energy 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 thermal energy in fluids (liquids and gases) where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves, which can occur through empty space.

Front

Example of conduction in everyday life?

Back

Walking on hot sand with bare feet.

Front

Example of convection in everyday life?

Back

Warm air rising and cool air sinking, such as in a room heated by a radiator.

Front

Example of radiation in everyday life?

Back

The sun warming your skin.

Front

What happens to air when it is heated?

Back

Heated air becomes less dense and rises.

Front

What happens to air when it cools?

Back

Cool air becomes denser and sinks.

Front

What type of heat transfer occurs when the sun warms the sand?

Back

Radiation.
