Back

Thermal energy is the total energy of the particles in a system.

Front

What happens to molecules when matter goes from a gas to a liquid?

Back

The molecules contract and slow down.

Front

What type of thermal energy transfer occurs through empty space?

Back

Radiation.

Front

What is temperature?

Back

Temperature is the average measurement of kinetic energy of molecules.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) due to uneven heating.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves.

Front

What is the relationship between thermal energy and temperature?

Back

Thermal energy is the total energy, while temperature is the average kinetic energy of particles.

Front

What is an example of conduction?

Back

An example of conduction is a metal spoon getting hot when placed in a hot soup.

Front

What is an example of convection?

Back

An example of convection is warm air rising and cool air sinking in a room.
