liquids don't sublimate, the definition of sublimation is a solid that changes directly into a gas with no liquid phase.
an example of this is dry ice, which go's straight from solid phase to gas phase.
It goes from solid to gaseous form without passing through a liquid phase.
because it usually sublimates from a solid (dry ice) to a gas bypassing the liquid stage.
It is usually a solid, which sublimates at room temperature to form a gas.
melt
Because iodine sublimates, as do the other solid halogens. That means they go from solid to gas without becoming a liquid first.
Carbon dioxide has no liquid form. The solid sublimates to gaseous form directly. Because it has no liquid form it can't be wet to the touch, like ice is, yet it looks like ice. Dry ice.
Green.
My chemistry is a litte rusty but I believe that Bromine is unusual because it sublimates - goes from solid phase to gaseous phase without going through liquid phase.
If u cool CO2 b low -78.5 C it will melt in2 a liquid. ( at -78.5 C CO2 sublimates )
Dry Ice. Unlike water, Carbon Dioxide doesn't melt, it sublimates; going directly from solid to gas without going through liquid.
Solid carbon dioxide has the look and feel of ice (and is even colder). But it does not melt to a liquid, but sublimates to form a gas. So it is always dry.
Dry ice doesn't melt. It sublimates at -78 0C, or -109 0F. Sublimation is a direct transition from a solid to a gas, skipping the liquid phase.
