Evaporation
________ occurs only at the surface of liquids where high energy particles can escape from the liquid's surface at low temperatures, below the b.p.
New cards
6
reverse
This is the ________ of melting and occurs at exactly the same temperature as melting, hence the melting point and freezing point of a pure substance are the same.
