Thermal Energy and Heat Transfer Flashcard

Front

What is conduction?

Back

The transfer of heat or electricity through a substance without any apparent movement of the substance itself.

Front

What is radiation?

Back

Radiation is the emission of energy as electromagnetic waves or as moving subatomic particles.

Front

What is heat transfer?

Back

The movement of thermal energy from one object or system to another due to a difference in temperature.

Front

Which of the following is an example of conduction?

Back

Touching a hot stove.

Front

What is the main source of radiation on Earth?

Back

Sun.

Front

What is convection?

Back

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

Front

What is thermal energy?

Back

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

Front

What is the difference between heat and temperature?

Back

Heat is the energy transferred between objects due to a temperature difference, while temperature is a measure of the average kinetic energy of particles in a substance.

Front

What is an insulator?

Back

A material that does not conduct heat well, preventing heat transfer.

Front

What is a conductor?

Back

A material that allows heat to pass through it easily.
