when iodine crysatals are heated, they turn from a solid into a gas (vapour). They start a black colour and as they gradually turn into a gas, they turn to a purple colour. At the end, there are no crystals left.
No, these are two different things. They will have slightly different chemical equations to show the differences that arise.
Iodine crystal is a molecular crystal. It consists of individual iodine molecules held together by van der Waals forces, rather than ionic bonds between ions.
iodine is made from diatomic iodine molecules,the two iodine atoms are covalently bonded with each other.the iodine molecules have dispersion forces so,the crystal is made from the dispersion forces between the iodine molecule.
You can conduct a conductivity test on an iodine crystal to confirm that iodine is a non-metal. If the crystal does not conduct electricity, it indicates that iodine is a non-metal because non-metals are typically poor conductors of electricity.
Heat is required to melt an iodine crystal because melting involves breaking the forces of attraction between iodine molecules in the crystal structure. When heat is applied, it adds energy to the crystal, allowing the molecules to overcome these forces and transition from a solid to a liquid state.
iodine is soluble in CHCl3. Liquid become purple in color.

When you burn a crystal, it can release toxic fumes, especially if it contains certain elements like lead or sulfur. Additionally, the crystal can also shatter or crack due to the high heat. It is not recommended to burn crystals for these reasons.
No, it is not recommended to put iodine on a burn. Iodine can further irritate the burn and delay the healing process. It is better to clean the burn with mild soap and water, and then cover it with a sterile bandage. If the burn is severe, seek medical attention.

It is crystal violet & stains all cells purple.

iodine
When iodine crystals are placed in water, they slowly dissolve to form an iodine solution. This solution will have a characteristic brown color, indicating the presence of iodine. Iodine is sparingly soluble in water, so the reaction may take some time to reach equilibrium.
Iodine is used to bind the Crystal Violet to the Gram Positive microbes.
Iodine is used in Gram staining as a mordant, which helps to bind the crystal violet dye to the cell wall of bacteria. This mordant-iodine complex forms larger complexes with the crystal violet dye, making it difficult for the dye to be washed away during the decolorization step. This allows for differentiation of Gram-positive and Gram-negative bacteria based on their ability to retain the crystal violet dye.
