Thermal Energy - Heat Transfer

Front

What is thermal energy?

Back

Thermal energy is the energy of particles in motion which can be described as heat.

Front

What are the three ways heat is transferred?

Back

Conduction, convection, and radiation.

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 through space in the form of waves.

Front

What is a thermal conductor?

Back

A thermal conductor is a material that allows heat to easily pass through it and escape.

Front

What is a thermal insulator?

Back

A thermal insulator is a material that does not allow heat to easily pass through it or escape.

Front

How does heat transfer in a pot on the stove?

Back

Heat transfer in a pot on the stove occurs primarily through convection.

Front

What happens to air when it is heated?

Back

When air is heated, it becomes less dense and rises, causing cooler air to sink.

Front

What is the role of temperature in heat transfer?

Back

Temperature is a measure of the average kinetic energy of particles; heat transfer occurs from areas of higher temperature to areas of lower temperature.
