Thermal Energy - Heat Transfer

Front

What is thermal energy?

Back

The energy of particles in motion which can be described as heat.

Front

What type of heat transfer occurs when two objects are touching?

Back

Conduction.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is convection?

Back

The transfer of heat through the movement of fluids (liquids or gases) where hot fluid rises and cold fluid sinks.

Front

What is radiation?

Back

The transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

What is a thermal conductor?

Back

A material that allows heat to easily pass through it and escape.

Front

What is a thermal insulator?

Back

A material that does not allow heat to easily pass through it or escape.

Front

How does heat transfer by convection occur?

Back

Through the circulation of hot air or water rising and cold air or water sinking.

Front

What happens to particles in a substance when it is heated?

Back

The particles move faster and spread apart, increasing the thermal energy.

Front

What is an example of conduction?

Back

Touching a hot stove and feeling the heat transfer to your hand.
