BET surface area testing principle is from 3 men names, Langmuir is from one. Usually BET surface area mean multi-layer adsorption, but Langmuir refers to monolayer adsorption. BET surface area principle reflects the real adsorption situation an process for most materials, so, be treated more important and trustable than Langmuir surface area. There area some analyzers( e.g. V-Sorb 2800S, V-Sorb 4800) can test both BET and Langmuir, also with pore size related, you can ask from them for a free test, because our insitutes got one already.

The surface area of a cylinder prism has round shape and the surface of a rectangular prism has a square shape.
Area is used to find the amount of square units insided of a 1- dimensional figure. The formula is: Length x Width= area Surface is quite different. Think of it this way. You have a cardboard box. If you cut each seam of the box and found the area of each section, added them together, you would have the surface area. The formula is: (Length x width x 2)+(width x height x 2)+(height x length x 2)= Surface area
Evaporation is a process that takes place at the surface of a liquid, therefore the rate of evaporation is directly related to the surface area. Twice as much surface area will give you twice as much evaporation.
Yes, it is.
In general, the dissolution rate is directly proportional to surface area. This is because the surface area tells you how much solute is exposed to the solvent. The greater the surface area, the more solute molecules that can bind to the solvent molecules, which means more dissolution.
