The change of state of a solid to a gas is called sublimation. Sublimation occurs when a solid substance bypasses the liquid state and transforms directly into a gas under specific conditions of temperature and pressure. During sublimation, the intermolecular forces holding the solid together are overcome, allowing the solid particles to escape into the gas phase without passing through the liquid phase.
Solid --> Liquid = melting Other changes of state: Solid --> Gas = sublimation Gas --> Solid = deposition Liquid --> Solid = freezing/solidification Gas --> Liquid = condensation Liquid --> Gas = vaporization
A change of phase, from solid to liquid, or liquid to gas, or gas to liquid, etc., is also sometimes called a change of state.
The sublimation of iodine crystals to produce purple gas is a physical change. This is because the change in state from solid to gas does not involve a change in the chemical composition of the substance. The purple color of the gas is due to the absorption and emission of specific wavelengths of light by the iodine atoms.

The direct change from a solid to a gas is called sublimation.
The change of state directly from solid to gas is called sublimation, and the change from gas to solid is called deposition.
a phase change: solid to liquid: melting liquid to solid: freezing liquid to gas: vaporization gas to liquid: condensation solid to gas: sublimation gas to solid: deposition
Sublimation is a change of state directly from a Solid to a Gas, or a Gas to a solid. There is no intermdiate liquid stage. Carbon dioxide ( gas) sublimes to Dry Ice (Solid Carbon dioxide).
Solid to Gas phase change is called Sublimation
Going from gas to solid is Deposition, from solid to gas is Sublimation

Sublimation is the change in state from solid to gas without passing through the liquid state. This process involves the solid material directly converting into a gas due to the addition of energy. An example is dry ice (solid carbon dioxide) sublimating into carbon dioxide gas.
A change in state involves a substance transitioning from one physical form to another, such as from solid to liquid (melting), liquid to gas (vaporization), or gas to liquid (condensation). This change is typically driven by changes in temperature or pressure.
Please note that a "change of state" involves TWO states, not just one. Using just the three most common states of matter: * A solid can change to a gas * A liquid can change to a gas * A gas can change to a liquid * A gas can change to a solid * A solid can change to a liquid * A liquid can change to a solid The first four changes in the list above involve gases.
