Unit 3 Heat Transfer Study Guide

Front

What is heat transfer?

Back

The movement of energy via particle motion from matter with a higher temperature to matter with a lower temperature.

Front

What is convection?

Back

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

Front

What happens to cold water molecules compared to hot water molecules?

Back

Cold water molecules move less than hot water molecules.

Front

What type of energy is found in food?

Back

Chemical energy.

Front

What is kinetic energy?

Back

The energy an object possesses due to its motion.

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy increases with the square of the speed of an object.

Front

What is conduction?

Back

The transfer of heat through direct contact between materials.

Front

What is radiation?

Back

The transfer of energy through electromagnetic waves.

Front

What is an example of convection?

Back

The movement of warm air rising and cool air sinking.

Front

What is thermal energy?

Back
