Sublimation is not a reaction, but a physical change (change of state or phase). The solid turns instantly to gas, rather than first going to liquid state. At the right temperature and pressure, this can happen.
A common example of this is dry ice (solid carbon dioxide) turns to carbon dioxide gas without first going through the liquid phase. This occurs, because liquid carbon dioxide cannot exist at 1 atmosphere pressure.
Sublimation can happen with solid water (ice) as well, at the right temperature. Ice cubes in a freezer can seemingly disappear over time.

What do you call when a solid turns straight into a gas?
A solid that turns directly into a gas is dry ice. Sublimation
What happens to the entropy in the reaction I2 s I2 g?
The entropy of the system increases during the sublimation of I2(s) to I2(g) because the randomness and disorder of the gas phase is higher compared to the solid phase. Therefore, the entropy of the reaction is positive.
Can iodine and naphthalene be separated by sublimation?
Yes, iodine and naphthalene can be separated by sublimation because they have different sublimation points. Iodine sublimes at a lower temperature compared to naphthalene, allowing for the selective separation of the two substances based on their sublimation properties.
The change in state from a solid directly to a gas without passing through the liquid state?
This process is known as sublimation. Sublimation occurs when a substance goes from a solid to a gas without passing through the liquid state. Examples of substances that undergo sublimation include dry ice (solid carbon dioxide) and mothballs (paradichlorobenzene).
Is burning woo sublimation?
Burning is a chemical reaction between a substance and oxygen. Sublimation is a type of physical state change produced by changes in temperature and/or pressure; it is not a chemical reaction. Sublimation is not the same as combustion.
Is sublimation fast reaction?
Not necessarily.
When a compound is released into the air what is the chemical reaction called?
Sublimation
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
What describes a way to turn a solid into a gas without a chemical reaction?
sublimation.
What is another type of vaporization besides sublimation?

Why is the sublimation of dry ice and the expansion of gases not chemical reations?
A chemical reaction is one that changes the chemical properties of a substance. Sublimation is just going from solid to a gas and is only a change of state.
What type of phase change is happening as a solid changes to gas without becoming to a liquid?
Sublimation occurs when solid changes directly to liquid without changing to solid state. Applying pressure and reducing temperature can liquefy gases.
Is burning wood sublimation?
Burning wood does not involve sublimation. Sublimation changes a solid to a gas without altering it chemically. Wood burning does involve destructive distillation. The wood is chemically destroyed, and parts of it go off as gasses, which then combust.
What is the process called when ice turns into water vapor?
I think the answer is sublimation
Is sublimation a vice versa process?
Yes, sublimation is a reversible process where a substance transitions between the solid and gas phases without passing through the liquid phase. This means that sublimation can occur both when a solid turns directly into a gas (deposition) and when a gas turns directly into a solid (desublimation).
What is it called when a solid changes directly into a gas?
It is called sublimation.
