Which phase change at standard temperature and pressure represents sublimation?

Substances on Earth can exist in three phases namely, solid, liquid or gas. The phase can be changed from one to other by any of six changes of phase: melting, condensation, freezing, vaporization, decomposition or sublimation.

Chemical process in which a solid turns to a gas without going to liquid stage is known as sublimation. It is an endothermic (absorbs heat) process. For example: Transformation of dry ice (solid carbon dioxide) to vapors to form clouds.

Hence, phase change at standard temperature and pressure which represents sublimation is solid turns to a gas without going to liquid stage.
