what is sublimation?
mere ko follow kro koi pls
Answers
Answer:
Sublimation is the direct transition from the solid state to vapor, and the heat absorbed by it is equal to the sum of the latent heats of fusion and of vaporization.
SUBLIMATION
Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. ... The opposite of sublimation is "deposition", where water vapor changes directly into ice—such a snowflakes and frost.When the surface layer of snow or ice turns into fog or steam without melting, this is an example of sublimation.
EQUATION
Calculate the heat of sublimation of the substance by dividing the heat absorbed by the substance, as calculated in step 2, by the mass of substance in grams. For example, if 47.5 g of substance was placed in the calorimeter, then the heat of sublimation would be 27,100 / 47.5 = 571 J/g.
REVERSE
The opposite of sublimation is "deposition", where water vapor changes directly into ice—such a snowflakes and frost.
WATER
The reverse process of sublimation is deposition (i.e., gas to solid).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.
