Intro to Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the kinetic energy of atoms and molecules in matter.

Front

What happens to temperature when the kinetic energy of molecules increases?

Back

The temperature increases.

Front

What does temperature measure?

Back

Temperature measures the average kinetic energy of the atoms in a substance.

Front

What happens to the vibration of atoms when thermal energy is removed?

Back

The atoms vibrate slower.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is the relationship between thermal energy and temperature?

Back

As thermal energy increases, the temperature of a substance typically increases.

Front

What are atoms and molecules?

Back

Atoms are the basic building blocks of matter, and molecules are groups of atoms bonded together.

Front

How does thermal energy affect the state of matter?

Back

Increasing thermal energy can change a substance from solid to liquid (melting) or from liquid to gas (evaporation).

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).
