the process is called sublimation
That one is easy. It becomes a gas. That process is called "Vaporation". The steam that comes out of the water is the gas. It only becomes a gas when the water boils.
When a gas changes directly to a solid it is called deposition.
When a gas changes directly to a solid it is called deposition.
When a liquid is heated and changes to its gaseous state, it is called vaporization.
Solid changing directly to a gas is called sublimation. In this process, the solid skips the liquid phase and turns directly into a gas when heated. This occurs when the vapor pressure of the solid exceeds the atmospheric pressure.
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
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.
Ice (solid water) changes to liquid water when heated. Wax solid changes to liquid wax when heated. Metal becomes molten when heated to its melting point. Paraffin wax solid changes to liquid paraffin wax when heated.
It is very interesting to know that camphor is solid at room temperature. However if it is heated even slightly, it changes into gaseous state.
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
sublimation
The direct conversion of a solid to a gas is called sublimation. In this process, the solid phase skips the liquid phase and transforms directly into a gas when heated.
