The process called when a solid turns directly into a gas is known as sublimation. During sublimation, substances transition from a solid state to a gaseous state without first becoming liquid. This phenomenon occurs under certain conditions, typically influenced by temperature and pressure. An example of sublimation can be seen in dry ice, which is solid carbon dioxide; it directly transforms into carbon dioxide gas at atmospheric pressure as it warms up. Sublimation is an essential process in various scientific and industrial applications, including freeze-drying, collection of certain gases, and certain phases in the development of snowflakes in nature.
