1. Sublimation The transitions of a substance from the solid phase directly to the vapour phase, or vice versa, without passing through an intermediate liquid phase.
2. Sublimation is the process of a solid changing form a gas to a solid without going to the liquid state and vice versa. An example of sublimation is the ice cubes in freezer over a period of time they will begin to sublimate due to the temperature. This also happens when you place your clothes on a line outside when it is below freezing. The water freezes then sublimates and your clothes will be dry but very cold.
There is one gas that changes to a solid directly at -109 degrees Fahrenheit and that is carbon dioxide. a gas can go to a solid if at the right temperature but some are very low to go directly to a solid so for an easier process they got to the liquid state by going to a higher temperature , so that then it can be frozen and then begin to sublimate example: Helium transforms to a liquid at -452.1 degrees Fahrenheit, if then frozen while in the liquid state it will then turn out to be a solid and begin to sublimate over a period of time. Hydrogen transforms to a liquid at 422.9 degrees Fahrenheit. If at that point in time it is frozen to a solid, that phase will start to sublimate over a period of time into a gas
3. Sublimation (in chemistry) is the process by which a solid is converted on heating directly into a gas, without going through a liquid state. Only a small number of solids sublime, carbon dioxide, CO2 and iodine, I2, being examples. Ammonium chloride, NH4Cl, sublimes on heating, but the vapour is a mixture of ammonia, NH3, and hydrogen chloride, HCl; on cooling, solid ammonium chloride is reformed. Some solids, which do melt to form a liquid, still evaporate quite rapidly if kept below their melting points; iodine and sulphur are examples. This is also sublimation, and can be used as a method of purification.
Solids, liquids, and gases are the three main, or fundamental phases of matter. Each one has a different density and a different level of stability. What determines the stability of each phase is the bond between it's atoms. The tighter the bond between it's atoms the more stable that phase of matter is. Solids are the most stable form of matter, followed by liquids, and then gases. Solids have a ...
