Chapter 5- Thermal Energy

Front

What is conduction?

Back

The transfer of energy from one particle of matter to another within an object or between two objects that are in direct contact.

Front

What is thermal energy?

Back

The total kinetic and potential energy of all the particles in an object.

Front

What is radiation?

Back

The transfer of energy by electromagnetic waves.

Front

How do car engines convert energy?

Back

Car engines convert chemical energy into thermal energy.

Front

Why does sand heat up faster than ocean water?

Back

Sand has a lower specific heat than water.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is convection?

Back

The transfer of heat by the movement of fluids (liquids or gases).

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What is the principle of heat transfer?

Back

Heat transfers from areas of higher temperature to areas of lower temperature.

Front

What is an example of conduction?

Back

A metal spoon getting hot when placed in a hot soup.
