What else can I help you with?
Can every iodine change from solid to gas?
Yes, iodine can undergo sublimation, a process where it changes from a solid to a gas without passing through the liquid phase. This is why iodine crystals can directly transform into purple vapor when heated.
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).
What is a solid nonmetal that gives purple vapor on heating?
Iodine is a solid nonmetal that gives off purple vapor when heated.
Why is sublimation of iodine is a physical process?
Sublimation is a physical process because it involves the direct transition of a substance from solid to gas phase without passing through the liquid phase. In the case of iodine, when it is heated, it directly converts from solid to gas without changing its chemical composition, making it a physical change.
Is iodine a solid lidquid or gas?
Iodine is a solid at room temperature and pressure. It sublimes directly from a solid to a gas when heated without passing through a liquid phase.
Why does solid iodine change when its heated?
Solid iodine is transformed by heating in a liquid at 113,7 oC.
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.
Can every iodine change from solid to gas?
Yes, iodine can undergo sublimation, a process where it changes from a solid to a gas without passing through the liquid phase. This is why iodine crystals can directly transform into purple vapor when heated.
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).
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 a solid nonmetal that gives purple vapor on heating?
Iodine is a solid nonmetal that gives off purple vapor when heated.
What state is iodine at room temperature?
Iodine is a solid when at 25 degrees centigrade (room temperature)
Why is sublimation of iodine is a physical process?

In the case of iodine, when it is heated, it directly converts from solid to gas without changing its chemical composition, making it a physical change.
Is iodine a solid lidquid or gas?
Iodine is a solid at room temperature and pressure. It sublimes directly from a solid to a gas when heated without passing through a liquid phase.
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 an element that is a shiny black solid and gives off a purple vapor when heated?
Iodine ------------------------------------------- The element you describe sounds like iodine, a good test to make sure that it is iodine is to see if the substance sublimes. This means a solid sample of iodine will turn straight from a solid into a gas with no liquid stage.
Which halogen is a grey solid?
Iodine is a grey solid halogen at room temperature. It has a shiny appearance and can sublimate into a purple vapor when heated.
