Sublimation

Postby Aarthi_Lakshmi_2A » Sat Jan 14, 2017 11:44 pm

I know that there is an enthalpy of sublimation, but it what cases would sublimation occur? How can the liquid state be skipped all together? Wouldn't the compound have to be liquid at some point as it transitions from solid to gas, even if it's only liquid for a minuscule period of time?

That is a very good question. An example of sublimation would be solid carbon dioxide, (also known as dry ice), sublimating at room temperature. A solid block of dry ice will start sublimating at room temperature without transitioning into a liquid state first.
