Vaporization of an element or compound is a phase transition from the liquid phase to gas phase. There are two sorts of vaporization: evaporation and boiling.

Evaporation is a phase transition from the liquid phase to gas phase that occurs at temperatures below the critical temperature.

Boiling is a phase transition from the liquid phase to gas phase that occurs at temperatures above the critical temperature.

The term vaporization has also been used to refer to the physical destruction of an object upon exposure to great heat; this includes human bodies, as noted in discussions of the effects of nuclear attack, including the 1945 bombings of Hiroshima and Nagasaki and the 1952 "vaporization" of the Marshall Island of Elugelab by the Ivy Mike thermonuclear weapon test..[1]

Vaporization is also what happened in a 1948 explosion at a chemical plant in Berlin, as 500 people were vaporized in a turn of events similar to that in Hiroshima.
