What solid sublimes on heating?
Some solids are Carbon dioxide, Snow, Iodine and Naphthalene
What state is the iodine in when it is heated?
When iodine is heated, it sublimes from a solid state directly into a purple-colored gas. It undergoes sublimation, which means it changes from a solid to a gas without passing through the liquid state.
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 iodine exist in solid state but it is a gas?
Iodine sublimes (i.e., goes from a solid to a gas) at room temperature and atmospheric pressure. However, it will exist as a solid for a very long time if it is kept in a closed container. As the iodine solid sublimes, the pressure will increase slightly within the closed container which will cause the iodine gas to reach an equillibrium state with the solid iodine (i.e., there will not be an increase in the amount of iodine gas in the container).
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 state of matter is iodine at room temperature?
At room temperature iodine is a solid halogen.

Which substance will sublime at 298K?
Iodine sublimes at 298K. Sublimation is the process in which a substance transitions directly from a solid to a gas without passing through the liquid state.
When iodine is heated does any iodine melt?
iodine is a substance that has an unusual property, it has the ability to sublimate, this means that it converts directly from a solid to a gas with no liquid stage at all. So no, no iodine will "melt" into a liquid, it will insted turn into a purple gas.
When iodinebecome to purple gas describe chemical properties?
Iodine sublimes into a purple gas without passing through a liquid phase. This is a change in physical state, which is a physical change.
Why is liquid iodine not visible if crystals are heated in the open air?
When iodine crystals are heated in open air, they sublimate directly from solid to gas without passing through a liquid phase, which means they skip the liquid state. This process is called sublimation. So, liquid iodine is not visible because it transforms directly from solid crystals to a gaseous form.
What is iodine vapour?
A "vapor" in chemistry is always the gas phase of a substance that is more familiar in one of its condensed phases: liquid or solid. Therefore, iodine vapor is the gas phase of the element iodine, and has the same molecular composition as the solid, I2. Iodine is a solid at standard temperature and pressure, but sublimes directly to gas phase, without any intermediate liquid phase, at only moderately higher temperatures than the standard.
Why iodine exist in solid state but it is a gas?
Iodine sublimes (i.e., goes from a solid to a gas) at room temperature and atmospheric pressure. However, it will exist as a solid for a very long time if it is kept in a closed container. As the iodine solid sublimes, the pressure will increase slightly within the closed container which will cause the iodine gas to reach an equillibrium state with the solid iodine (i.e., there will not be an increase in the amount of iodine gas in the container).
What is a dark grey solid that sublimes to form a violet vapor?
Iodine ( I2 ) the fourth halogen (after F2 ,Cl2 -both gases- and Br2 -liquid- ) Iodine has a shiny, dark grey, metallic look (but it is not a metal) with crystal forms which subliMATES to violet vapour. It is slightly soluble in water, better in a Iodide solution (to form I3- complex ions) and in ethanol (red-brown tincture)
