Thermal Energy and Heat Transfer

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of all the particles in an object, which is related to its temperature.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of the individual particles in an object.

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.

Front

Which particles have the highest kinetic energy?

Back

Particles in steam have the highest kinetic energy compared to particles in ice, water, or boiling water.

Front

How does heat transfer when touching a hot stove?

Back

Heat transfers from the stove to your hand.

Front

What happens to particles as they cool down?

Back

As particles cool down, they slow down.

Front

In which direction does heat transfer occur?

Back

Heat transfer occurs only from warm objects to colder ones.

Front

What is the role of thermal energy in temperature changes?

Back

Thermal energy affects the temperature of an object; as thermal energy increases, temperature increases.
