Flashcard: Thermal Energy Amplify Ch.1

Front

What is temperature?

Back

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

Front

What happens to molecules when they get hotter?

Back

When an object's molecules get hotter, they move faster.

Front

What is the best definition of temperature?

Back

A measure of the average speed of the molecules of a substance.

Front

What happens to molecules when an object gets colder?

Back

When an object gets colder, its molecules move slower.

Front

What is absolute zero?

Back

Absolute zero is when molecules have zero speed or movement.

Front

What is thermal energy?

Back

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

Front

How does thermal energy relate to temperature?

Back

Thermal energy is related to temperature because higher temperatures indicate 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).

Front

What is radiation?

Back

Radiation is the transfer of thermal energy through electromagnetic waves.
