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.

Which type of reaction rate is the fastest?
Explosion is a type of fast reaction.
What type of reaction is acetone reacted with triiodomethane?
An iodoform reaction is the type of reaction when acetone reacts with triiodomethane.
What is the change from a solid directly to a gas is called?
When a solid turns directly into a gas without becoming a liquid it is called sublimation. The reverse of this process is called deposition.
What is the name of a solid turning into a gas?
Sublimation is the process in which a solid turns directly into a gas without passing through the liquid state.
How do you separate naphthalene from sand?
by sublimation
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.
Is sublimation exothermic or endothermic?
Sublimation is an endothermic phase transition from solid to gaseous state.
When a compound is released into the air what is the chemical reaction called?
Sublimation
What describes a way to turn a solid into a gas without a chemical reaction?
sublimation.
Is condacation and sublimation a type of evapazation?
Yes it is
Is sublimation a vice versa process?
Sublimation is not a chemical reaction but a phase transition phenomenon; the reverse phenomenon is named deposition.
What is another type of vaporization besides sublimation?
cvbnm,.
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.
A change of state where energy is given off?
This process is called exothermic reaction, where energy is released in the form of heat. It typically involves a change from a higher energy state to a lower energy state, resulting in the release of energy to the surroundings. An example would be the solidification of molten lava into solid rock, releasing heat energy in the process.
How do you draw a sublimation curve?
To draw a sublimation curve, plot temperature on the x-axis and pressure on the y-axis. Follow the curve that shows the conditions where the substance transitions directly from solid to gas without passing through the liquid phase. The curve slopes upward as pressure increases, indicating the sublimation point.
