Add your answer. This is kinda horrible, but: if people hang themselves...? and don't manage to break their neck, do blood vessels in their head burst? is the circulation cut off to and from their head and brain, so that the blood pressure increases in the head?
Lesson Summary. Sublimation is a type of phase transition, or a change in a state of matter, just like melting, freezing, and evaporation. Through sublimation, a substance changes from a solid to a gas without ever passing through a liquid phase. Dry ice, solid CO2, provides a common example of sublimation.
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water. The opposite of sublimation is deposition, where water vapor changes directly into iceâsuch a snowflakes and frost. It is not easy to actually see sublimation occuring, at least not with ice. One way to see the results of sublimation is to hang a wet shirt outside on a below-freezing day.
