CONDUCTION,CONVECTION AND RADIATION

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat by the movement of fluids (liquids or gases) due to differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, which can occur in a vacuum, such as sunlight reaching Earth.

Front

What is the original source of most of the energy that people use?

Back

Energy that reaches Earth by radiation from the sun.

Front

How does heat transfer occur?

Back

Heat transfers from a warmer object to a cooler object.

Front

What happens to warm air in a room?

Back

Warm air rises because of convection.

Front

What type of heat transfer occurs when walking on warm sand?

Back

Conduction.

Front

Which example best describes heat transfer by radiation?

Back

A camp fire warming hands.

Front

What is an example of conduction in everyday life?

Back

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

Front

What is an example of convection in action?

Back

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