when iodine is heated it gives voilet vapours
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
The fumes given off when crystals of iodine are heated are purple in color.
Sublimation is the process where solid iodine directly turns into iodine vapor without passing through the liquid phase. When the solid iodine is heated, it sublimes into vapor which then collects in the flask as the vapor cools down and condenses.
Solid iodine is transformed by heating in a liquid at 113,7 oC.
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
Because it sublimes that is it directly forms into a solid
You think to iodine.
Iodine vaporizes when heated gently because of sublimation, where the solid iodine directly transforms into iodine vapor without passing through a liquid phase. This occurs due to the weak intermolecular forces between iodine molecules, allowing them to escape from the solid crystal lattice and form a gas.
because when they are heated they are sticky and they only fix to fingers
Iodine is a brittle solid at room temperature and does not exhibit ductility. It easily sublimes into a gas when heated.
Iodine is a black solid that sublimes directly to a purple vapor without passing through a liquid phase when heated gently.
Iodine is an element that sublimes when gently heated. Sublimation is the process of a substance transitioning directly from a solid to a gas phase without passing through the liquid phase.
