Thermal Energy Transformations

Front

What is thermal energy?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat 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.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as light or heat waves.

Front

How does heat travel in the atmosphere?

Back

Heat travels from hot areas to cold areas.

Front

What happens to warm water in the ocean?

Back

Warm water rises to the surface, while cold water sinks.

Front

Why do helium balloons rise?

Back

Helium balloons rise because helium is less dense than the surrounding air.

Front

What is the difference between conduction and convection?

Back

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

Front

What is an example of conduction?

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?

Back

An example of convection is warm air rising and cool air sinking in a room.
