What is conduction?

Back

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

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight warming your skin.

Front

What is condensation?

Back

Condensation is the process where water vapor turns into liquid water, often seen as droplets on a cold surface.

Front

What is evaporation?

Back

Evaporation is the process where liquid water turns into water vapor, usually occurring at the surface of the liquid.

Front

What is melting?

Back

Melting is the process where a solid turns into a liquid when heat is applied.

Front

What is freezing?

Back

Freezing is the process where a liquid turns into a solid when heat is removed.

Front

What happens to particles during heating?

Back

Particles gain energy and move faster as temperature increases.

Front

What happens to particles during cooling?

Back

Particles lose energy and move slower as temperature decreases.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two objects in contact do not exchange heat, meaning they are at the same temperature.
