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.
What else can I help you with?
Why is iodine heated gently?
Because it sublimes that is it directly forms into a solid
What element sublimes when gently heated?
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.
Separation of iodine and alcohol?
The separation of iodine and alcohol can be achieved through a process known as distillation. In this process, the mixture is heated to separate the components based on their boiling points. Iodine has a higher boiling point than alcohol, so it will remain in the distillation flask while alcohol will vaporize and can be collected in a separate container.
What gas is produced when iodine are heated?
When iodine is heated, it sublimes directly from a solid to a purple gas. The gas produced is diatomic iodine molecules (I2).
How could iodine be separated from salt?
Iodine can be separated from salt by the process of sublimation.Sublimation is the process of conversion of a material from solid state to gaseous state without undergoing liquid state.Some sublimate objects are ammonium chloride,iodine,moth balls,camphor,etc.
Why is iodine heated gently?
Because it sublimes that is it directly forms into a solid
What black solid forms a purple vapour when heated gently?
Iodine is a black solid that sublimes directly to a purple vapor without passing through a liquid phase when heated gently.
What element sublimes when gently heated?
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.
When iodine is heated?
when iodine is heated it gives voilet vapours

How does iodine crystal changes into vapours?
Iodine crystals undergo sublimation when heated, meaning they transition directly from a solid state to a gaseous state without going through a liquid phase. When heated, the iodine crystals absorb heat energy, causing the molecules at the surface to break free from the crystal lattice and enter the gas phase.
What is the colour of the fumes given off when crystals of iodine are heated?
The fumes given off when crystals of iodine are heated are purple in color.
What process causes iodine vapor to collect in a flask of solid iodine?
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.
Why does solid iodine change when its heated?
Solid iodine is transformed by heating in a liquid at 113,7 oC.
What is a solid purple-black non metal which changes to a deep purple gas when heated?
Iodine is a purple-black non metal that changes to a deep purple gas when heated.
