Front

What is heat transfer?

Back

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

Front

What are the three main methods of heat transfer?

Back

Conduction, convection, and radiation.

Front

Define conduction.

Back

The transfer of heat through direct contact between materials.

Front

Define convection.

Back

The transfer of heat by the movement of fluids (liquids or gases) due to differences in density.

Front

Define radiation.

Back

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