5 True/False questions
What are the particles doing during condensation? → particles of a solid do not pass through the liquid state as they form gas
sublimation → change from a liquid to a gas
evaporation → when vaporization only takes place on the surface of a liquid
melting point → the temperature at which a liquid boils
What is happening to the molecules during vaporization? → the particles in a liquid gain enough energy to move independantly, forming a gas
