Frequently asked questions
What is the difference between sublimation and evaporation?
Evaporation is a liquid turning into a gas, such as a puddle drying up. Sublimation skips the liquid stage entirely, going straight from solid to gas — dry ice and mothballs are the standard examples.
What is the opposite of sublimation?
Deposition, sometimes called desublimation: a gas turning directly into a solid without becoming liquid first. Frost forming on a cold window is deposition.
Is sublimation endothermic or exothermic?
Endothermic. Breaking a solid apart into free gas molecules requires energy, so a subliming substance absorbs heat from its surroundings — which is why dry ice feels intensely cold.
What is the meaning of sublimation?
"sublimation" (noun) means the change of a solid directly into a gas without passing through a liquid stage, and sometimes the reverse change from gas straight to solid.
