1. Sublimation The transitions of a substance from the solid phase directly to the drying up phase, or vice versa, without passing through an intermediate melted phase.
2. Sublimation is the cover of a solid changing form a gas to a solid without going to the liquid state of matter and vice versa. An employment of sublimation is the ice cubes in freezer everyplace a period of while they will have to airt due to the temperature. This also happens when you place your clothing on a line outside when it is below freezing. The water freezes and then subtilises and your clothes will be dry but very cold. thither is one gas that changes to a solid directly at -109 degrees Fahrenheit and that is carbon dioxide. a gas brook go to a solid if at the right temperature but few be 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 flash-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 plant directly into a gas, without going through a liquid state. Only a small number of solids sublime, carbon dioxide, carbonic acid gas and iodine, I2, being examples.
Ammonium chloride, NH4Cl, sublimes on heating, but the vapour is a mixture...
Not really an essay. Nevertheless, its nice to see that you have included a dictionary definition of sublimation along with some examples. I dont notice why you have repeated yourself THREE TIMES. I carry off it these are three definitions are from three different dictionaries, books or whatever?. If so, then you should cite your sources (http://www.noodletools.com/quickcite/).
In conclusion, there are some clear and well written definitions here. GOOD stage business!
