What is deposition in terms of phase changes?

Back

Deposition is the phase change from gas to solid.

Front

What is the kinetic molecular theory?

Back

It explains the behavior of gases in terms of particles in constant motion.

Front

What is the difference between boiling and evaporation?

Back

Boiling occurs at a specific temperature throughout the liquid, while evaporation occurs at the surface at any temperature.
