Energy transfer

Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another.

Front

In which direction does energy (heat) move between objects?

Back

Energy moves from a hotter object to a colder object.

Front

What is conduction?

Back

Conduction is the transfer of energy through direct contact between materials, where atoms collide with each other.

Front

What is convection?

Back

Convection is the transfer of energy through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of energy in the form of waves, such as light or heat, without the need for a medium.

Front

What happens when you add ice to a warm drink?

Back

Energy moves from the warm drink to the ice, causing the drink to cool down and the ice to melt.

Front

What is an example of conduction in everyday life?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of convection in action?

Back

An example of convection is the rising and falling of wax in a lava lamp due to temperature differences.

Front

What is an example of radiation?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the role of temperature in energy transfer?

Back

Temperature differences drive energy transfer; energy moves from areas of higher temperature to areas of lower temperature.
