Scientists Say: Sublimation
This is what happens when matter goes straight from solid to gas
Sublimation (noun, “SUB-lim-A-shun”)
This is the process in which a substance goes directly from a solid state to a gas, without passing through the liquid phase. Matter exists in four phases: solid, liquid, gas and plasma. As matter heats up, solid melts to liquid, liquid evaporates to gas and gas becomes a plasma. But when the right conditions are met, a solid can sublimate, going straight from a solid to a gas.
In a sentence
