Energy Conservation and Transfer

Front

What is energy conservation?

Back

Energy conservation is the practice of reducing energy use to save resources and reduce environmental impact.

Front

What is an insulator?

Back

An insulator is a material that does not allow electricity or heat to pass through it easily.

Front

What is a conductor?

Back

A conductor is a material that allows electricity or heat to flow through it easily.

Front

Which material is the best conductor of heat?

Back

Copper is the best conductor of heat at room temperature.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat.

Front

How does heat transfer occur in a pan of soup on a stove?

Back

Heat is transferred from the stove to the pan (conduction), and then from the pan to the soup (convection).

Front

What happens to hot objects when they cool down?

Back

Hot objects lose energy to the surrounding air, causing them to cool.

Front

What is the role of air in heat transfer?

Back

Air can act as an insulator or a medium for convection, transferring heat away from hot objects.
