Thermal Energy Transfer

Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another due to a temperature difference.

Front

What are the three methods of thermal energy transfer?

Back

Conduction, Convection, and Radiation.

Front

Which method of thermal energy transfer occurs through direct contact?

Back

Conduction.

Front

What is convection?

Back

The transfer of thermal energy through the movement of fluids (liquids and gases) caused by differences in temperature and density.

Front

What is radiation?

Back

The transfer of thermal energy through electromagnetic waves, which can occur in a vacuum.

Front

What is a good conductor of thermal energy?

Back

Materials like metals (e.g., copper, aluminum) that allow heat to pass through them easily.

Front

What is an insulator?

Back

A material that does not conduct heat well, such as plastic, wood, or rubber.

Front

How does temperature relate to kinetic energy?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance; they are directly proportional.

Front

What happens to the thermal energy of a substance when it is heated?

Back

The thermal energy increases, causing the particles to move faster.

Front

What is an example of thermal energy transfer into a system?

Back

A pot of water boiling on a stove.
