This process is called Sublimation.
A substance which changes state directly from a solid to a gas is said to have sublimed.
Those substances which undergo the process of sublimation change directly from solid to gas or from gas to solid. Example:- Ammonium chloride, Camphor
Sublimation is the process in which solid changes directly to gas and gas changes directly to solid without any liquid phase
You should know the names of the process for these phase transitions. sublimation deposition SOLID ============> GAS ==============> SOLID melting freezing SOLID ============> LIQUID =============> SOLID (solidfication) condensation vaporization GAS =============> LIQUID =============> GAS
The kinds of changes in substances that are always physical changes are changes in the state. This is the change from solid, to liquid and then to gas and the reverse.

Iodine
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
Sublimation is the process in which solid changes directly to gas and gas changes directly to solid without any liquid phase
Iodine for example.
Melting: the substance changes back from the solid to the liquid. Condensation: the substance changes from a gas to a liquid. Vaporization: the substance changes from a liquid to a gas. Sublimation: the substance changes directly from a solid to a gas without going through the liquid phase.
The process in which solid directly changes into gas is called sublimation. Solid carbon dioxide is a substance that changes directly into gas without melting. Sublimation happens because these substances have higher vapor pressure than melting point.
The name of the process in which a solid changes directly into a gas is called sublimation.
