Thermal Energy and Heat Transfer

Front

What happens to molecular motion when temperature is increased?

Back

Molecular motion increases.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases).

Front

Give an example of convection in everyday life.

Back

Heating soup in a pan, where the soup circulates as it heats.

Front

What is conduction?

Back

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

Front

Give an example of conduction.

Back

A pot making contact with a hot stove.

Front

What is radiation?

Back

Radiation is the transfer of heat through electromagnetic waves.

Front

Give an example of radiation.

Back

The warmth felt from sunlight.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance.

Front

What is heat?

Back

Heat is the movement of thermal energy from a warmer object to a cooler object.

Front

What is temperature?

Back

Temperature is a measure of the average kinetic energy of particles in a substance.
