Thermal Energy Transfer Flashcard

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in an object.

Front

What is heat transfer?

Back

Heat transfer is the movement of thermal energy from one object or substance to another due to a temperature difference.

Front

What are the three methods of heat transfer?

Back

The three methods of heat transfer are conduction, convection, and radiation.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

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

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

Front

How does thermal energy move in a refrigerator?

Back

Thermal energy moves from the hot soup to the cold air in the refrigerator, cooling the soup.

Front

What does a thermogram display?

Back

A thermogram displays the temperature of an object, showing areas of heat and cold.

Front

Why is understanding thermal energy transfers important for energy auditors?

Back

Energy auditors need to understand thermal energy transfers to assess energy efficiency and recommend improvements.

What role does convection play in Earth's oceans?

Back

Convection circulates water in Earth's oceans, distributing heat and nutrients.
