Review: Thermal Energy Amplify Ch.1

Front

What is absolute zero?

Back

Absolute zero is when molecules have zero speed or movement.

Front

How do molecules in hot air move?

Back

Molecules in hot air move fast.

Front

What is the definition of 'average'?

Back

A number that describes a set of data and can be calculated by adding all the numbers in a list and then dividing by the number of numbers.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is.

Front

What is a molecule?

Back

A molecule is a group of atoms joined together in a particular way.

Front

What happens to molecular movement as temperature decreases?

Back

As temperature decreases, molecular movement slows down.

Front

What is thermal energy?

Back

Thermal energy is the total energy of all the particles in an object.

Front

How does thermal energy relate to temperature?

Back

Thermal energy is related to temperature; higher temperature means higher thermal energy.

Front

What is conduction?

Back

Conduction is the transfer of thermal energy through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of thermal energy through the movement of fluids (liquids and gases).
