Intro to Thermal Energy

Front

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

Back

The atoms vibrate slower.

Front

What type of chemical reaction can be used to heat up other substances?

Back

A chemical reaction that releases energy.

Front

What is thermal energy derived from?

Back

Thermal energy comes from the kinetic energy of the atoms and molecules that make up the matter.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What occurs when thermal energy is removed from a substance?

Back

A substance might freeze.

Front

What is the relationship between thermal energy and temperature?

Back

Thermal energy is the total energy of all the particles in a substance, while temperature measures the average kinetic energy of those particles.

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.

Front

How does thermal energy affect the state of matter?

Back

Thermal energy can change the state of matter, such as from solid to liquid (melting) or from liquid to gas (evaporation).
