Thermal Energy Transfer Concept Flashcard

Front

What is convection?

Back

The movement of gas or liquid in which warmer parts move up and the colder parts move down.

Front

What is conduction?

Back

The transfer of thermal energy through direct contact between materials.

Front

What is radiation?

Back

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

Front

What is thermal energy?

Back

The total kinetic energy of particles in a substance, related to temperature.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection involves the movement of fluids.

Front

What is an insulator?

Back

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

Front

What is a conductor?

Back

A material that allows heat to pass through easily, such as metals.
