Thermal Energy: Heat Transfer 6.2.3

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 heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact with each other reach the same temperature and no heat flows between them.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through a solid material without the movement of the material itself.

Front

What is convection?

Back

Convection is the transfer of heat through fluids (liquids and gases) caused by the movement of the fluid itself.

Front

What is radiation?

Back

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

Front

How does temperature affect particle movement?

Back

As temperature increases, the particles move faster, leading to greater kinetic energy.

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 warm air rising and cool air sinking in a room heated by a radiator.
