Front

What is thermal energy transfer?

Back

The process of heat moving from one object or substance to another.

Front

What are the three main methods of thermal energy transfer?

Back

Conduction, convection, and radiation.

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 and gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves, without the need for a medium.

Front

What is temperature?

Back

A measure of the average kinetic energy of the particles in a substance.

Front

Which material is a better conductor of heat: metal or wood?

Back

Metal is a better conductor of heat than wood.

Front

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

Back

Molecules move faster and spread apart as the substance gets warmer.

Front

What is the relationship between temperature and density in liquids?

Back

Generally, warmer liquids are less dense than cooler liquids.

Front

What is an example of conduction in everyday life?

Back
