Thermal Energy Transfer Review

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of the particles in a substance, which is related to its temperature.

Front

What is conduction?

Back

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

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat energy through electromagnetic waves, such as light, without the need for a medium.

Front

What is a convection current?

Back

A convection current is the circular motion of fluid particles when warm particles rise and cold particles sink.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a pot of boiling water.

Front

What is an example of convection?

Back

An example of convection is the movement of water in a boiling pot, where warm water rises and cool water sinks.

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 difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is the role of temperature in thermal energy transfer?

Back

Temperature determines the direction of heat transfer; heat flows from higher temperature areas to lower temperature areas.
