Can iodine ever be in the liquid state or it just sublimes on heating?
MSaad
Iodine can exist as a solid, liquid, or gas. Its normally solid at STP, but with slow heating you can get it into its liquid form. It sublimes, so the heat must be well controlled.
After he pours liquid bromine, this person then shows some liquid iodine.

How does iodine crystal changes into vapours?
Iodine sublimes- i.e it changes from solid to gas without going though a liquid phase.
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).
Why ammonium chloride not exists in liquid state?
Because it changes directly from solid to gas when heated. It sublimes.
Is iodine a physical property or a chemical property?
Iodine is an element and its special property is sublimation, this is a physical change from solid iodine to gasous iodine with no liquid phase(or state) in between.
On heating sublime substances like iodine and camphor they directly change from solid to gas?
On heating iodine and camphor directly converted into gases and no liquid state is appears in between this process because the intermolecular forces between the molecules in such types of solids is less than ordinary solids, therefore high energy molecules at solid surface over come the attractive forces and directly converted into vapours.

Iodine sublimes- i.e it changes from solid to gas without going though a liquid phase.
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.

What is a dark grey solid that sublimes to form a violet vapor?
The substance you are describing is likely iodine. Iodine is a dark grey solid that can sublime directly from a solid to a vapor without going through the liquid state. When iodine sublimes, it forms a violet vapor.
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 ammonium chloride not exists in liquid state?
Because it changes directly from solid to gas when heated. It sublimes.
Is heating liquid honey a change of state?
No. Simply heating honey, while making it less viscus, does not change its state. It remains a liquid. Unless heating is prolonged enough to cause evaporation, the honey will remain a liquid, so no change of state occurs by simply heating.
Is solid iodine sublimes into purple vapor a physical or chemical change?
Sublimation is a physical change, as ALL changes of state of matter (boiling, freezing, condensing, melting) are physical.
Is iodine a physical property or a chemical property?
Iodine is an element and its special property is sublimation, this is a physical change from solid iodine to gasous iodine with no liquid phase(or state) in between.
Change from a soild to a liquid state usually by heating?
melting
What is an example of sublimation that is not dry ice?
Iodine crystals will sublimate to iodine gas without going through a perceivable liquid state.
The change of state from a liquid to a gas?
It's called evaporation, generally caused by the heating of a liquid.
