You put it in a Freezer with a temperature of 30 degrees Fahrenheit or colde

Sorry to break it to you, but you can't get liquid iodine. (Well, you can. But that's EXTREMELY difficult, and it requires a change in atmospheric pressure.) Iodine's melting point is 113.7 degrees Celsius. This means that if you DO have liquid Iodine, dropping it below 113.7 degrees will cause it to form it's solid.
What you probably have is a liquid solution of iodine. This will most probably be potassium Iodide; you'll need something to displace the iodide ion from the solution.
This would either mean reacting it with Bromine ions, Chlorine ions, or Fluorine ions.
All of these reactions are extremely hazardous, and I do not recommend conducting them yourself.
If you need Iodine crystals that badly, I suggest buying them from a chemical store.
As with all matter, it can be any of these phases depending on temperature and pressure. At STP it is a black solid. Keeping the pressure constant but slowly raising the temperature it sublimes (i.e. transitions directly from solid to gas without becoming liquid) to a violet colored gas.The triple point (the temperature and pressure at which a material is simultaneously solid, liquid, and gas) of iodine is 386.65 K, 12.1 kPa or 236.30 F, 1.755 psi.
Iodine exists as I2. The crystal of iodine is formed simply by the interaction of iodine molecules as a result of Van de Waals forces, which allows for these molecules to bond together to form a solid.
In order for something to be considered a change some sort of change must occur. A crystal is an object, not a type of change. Dark violet iodine crystals are pieces of relatively pure elemental iodine.
Iodine crystals are considered a solute when they are dissolved in a solvent, such as water or alcohol. In this context, the iodine crystals dissolve to form a solution, with the solvent being the substance that dissolves the solute. However, when discussing iodine in its solid form, it is not a solvent but rather a solid compound that can be used to create solutions.
Solid crystals have a fixed, ordered arrangement of molecules or atoms, while liquid crystals have a partially ordered structure that can flow like a liquid but still exhibit some properties of a solid. Solid crystals have a defined melting point where they transition to a liquid state, while liquid crystals have a range of temperatures over which they exhibit liquid-like and solid-like properties.
You think probably to sublimation of iodine.
Iodine crystals are solid, crystalline form of elemental iodine, while iodine solution is a liquid mixture of elemental iodine and either alcohol or water. Iodine crystals are typically used for storage and long-term preservation, while iodine solution is commonly used for disinfection and medical purposes.
When iodine crystals are heated in open air, they sublimate directly from solid to gas without passing through a liquid phase, which means they skip the liquid state. This process is called sublimation. So, liquid iodine is not visible because it transforms directly from solid crystals to a gaseous form.
One method to separate iodine crystals from a mixture of iodine and sand is by using sublimation. Heat the mixture, and the iodine will sublimate (turn into gas) leaving the sand behind. The iodine gas can then be collected and cooled to form iodine crystals.
Iodine is a halogen whose crystals sublime. When iodine is heated, it changes directly from a solid to a gaseous state without passing through a liquid phase.
Iodine crystals will sublimate to iodine gas without going through a perceivable liquid state.
Sublimation is the process where a substance transitions from a solid directly into a gas without passing through the liquid phase. Iodine and bromine are examples of substances that undergo sublimation at room temperature, producing colored vapors. The solid crystals of these elements skip the melting phase and turn into vapor when heated.
Iodine crystals can be removed from a mixture by sublimation, where the crystals are heated to turn directly into vapour without melting. The vapour can then be condensed back into solid iodine crystals. This technique allows for the separation of iodine from other components in the mixture.
By heating it at low temperatures.
Iodine crystals are a pure substance.
iodine is soluble in CHCl3. Liquid become purple in color.
Iodine crystals are very poor conductors of heat and electricity
