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 atoms when thermal energy is removed from a substance?

Back

The atoms vibrate slower.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What does temperature measure?

Back

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

Front

What occurs when thermal energy is removed from a substance?

Back

The substance may freeze.

Front

What is the relationship between thermal energy and temperature?

Back

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

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.
