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.
alternates a form without changing what kind of matter there is : Sublimation: a change of stage directly from a solid to a gas : Melting point: the tempature when a substance melts: Boiling point: the tempature when a substance boils: Freezing point: the tempature when a substance freezes : Thermal expansion: the increase in an object's volume due to a change in heat
