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.
An example of sublimation is dry ice changing from a solid into carbon dioxide vapor at room temperature. Sublimation also occurs in nature, especially in high-altitude areas such as Mount Everest. The combination of low air pressure, intense sunlight and cold temperatures causes snow and ice to vaporize without turning into liquid.
