Question

•define sublimation.
•define evaporation.
•define sedimentation and decantation.
​

Answer 1

Answer:

Sublimation:

Sublimation is when a solid transitions into a gas, bypassing the liquid state. An example of this is when solid carbon sublimates into a gas as dry ice.

Decantation:

Decantation is when a mixture of liquids is allowed to separate, such that an element of the mixture may be removed. An example of decantation is when wine or beer is poured slowly to prevent sediments entering the glass with the alcohol.

Sedimentation:

Sedimentation is when particulates fall out of a mixture. An example is when you scoop up water from a lake or river, and over time a layer of dirt forms on the bottom.

Evaporation:

Evaporation is a type of vaporization that occurs on the surface of a liquid as it changes into the gas phase. The surrounding gas must not be saturated with the evaporating substance. When the molecules of the liquid collide, they transfer energy to each other based on how they collide with each other.
