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.
Why iodine vaporize when heated gently?
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 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 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 shiny black solid but gives off a purple vapor when heated.?
You think to iodine.
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 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.
What is shiny black solid but gives off a purple vapor when heated.?
You think to iodine.
What is the halogen that forms a purple vapor when heated?
The halogen that forms a purple vapor when heated is iodine. When iodine crystals are heated, they sublimate, transitioning directly from a solid to a gas, producing a characteristic violet or purple vapor. This property is due to the molecular structure of iodine, which allows it to easily vaporize at elevated temperatures.
