sublimation
the most common example is iodine. it is a black solid but when heated it converts directly to a purple gas. i can never forget this fact because i accidentally dropped iodine sample on Bunsen burner while doing my chemistry practical in school.
The process of gas turning directly into a solid is called deposition. This occurs when the gas vapor cools and transforms directly into a solid without passing through the liquid phase.
A solid that turns directly into a gas is dry ice. Sublimation
Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through the liquid phase. In sublimation, the solid's particles gain enough energy to break free from their fixed positions and move into the gas phase. This process is opposite to deposition, where a gas directly turns into a solid.
The change of state directly from solid to gas is called sublimation, and the change from gas to solid is called deposition.
Changing from a gas to a solid is called deposition.Since the opposite process... going from a solid to a gas... is sublimation, sometimes the gas-to-solid transition is called "desublimation."
The PHASE change of solid TO gas is called Sublimation.
When solid is heated and melt then it will change into gas
Sublimation
Desublimation
Deposition
When a substance goes from a gas to a solid it is called deposition.
"sublimation"
The process of changing a gas directly to a solid is called deposition. This involves the gas molecules losing energy and transitioning from a gaseous state to a solid state without passing through the liquid phase.
Deposition, or desublimation, is the transition process directly from gas to solid.The reverse (the transition directly from solid to gas) is called sublimation.
The process of changing a solid directly to a gas skipping the liquid stage is called sublimation.
Iodine. Also, the process is called sublimation (phase change from solid --> gas)
The process of gas turning directly into a solid is called deposition. This occurs when the gas vapor cools and transforms directly into a solid without passing through the liquid phase.
