Vocab Thermal Energy Trasnfer

Front

What is thermal energy transfer?

Back

The process of energy moving from one object to another due to a temperature difference.

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 or gases).

Front

What is radiation?

Back

The transfer of heat through electromagnetic waves, such as sunlight.

Front

What happens to the temperature of an object when it absorbs thermal energy?

Back

The temperature of the object increases.

Front

What is thermal expansion?

Back

The increase in volume of a material as it is heated.

Front

Why do sidewalks and bridges have gaps or joints?

Back

To allow for thermal expansion and contraction without causing damage.

Front

What is a good thermal insulator?

Back

Materials that do not conduct heat well, such as wood, rubber, or fiberglass.

Front

What happens to most materials when they are heated?

Back

They expand due to increased kinetic energy of their particles.
