Sublimation

The video tutorial explains the three states of matter: solid, liquid, and gas, and how substances can transition between these states through processes like freezing and sublimation. Freezing is when a liquid becomes a solid, exemplified by water turning into ice. Sublimation, a less common process, involves a solid becoming a gas without passing through a liquid state, as seen with dry ice and iodine. The tutorial highlights that matter can change states in surprising ways, challenging the notion that solids only melt and liquids only evaporate.
