Heat Transfer Flashcard

Front

What is heat transfer?

Back

The process of thermal energy moving from one object or substance to another.

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 through the movement of fluids (liquids and gases) caused by differences in temperature.

Front

Define radiation.

Back

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

Front

What happens to molecules when an object is heated?

Back

The molecules move faster.

Front

Give an example of conduction.
