no, it can not be separated by a physical process.
Distance is separated in space or time.
A compound that can be separated by electrolysis must be in the LIQUID state of matter.
Sugar and water can be separated by using a couple different methods. One method is by using an apparatus for distillation. Another is by using evaporation.
A capacitor
Air is separated by the differnet gases going away.
Air is separated in components by fractional distillation.
These gases are separated by condensation and distillation
Air components are separated by fractional distillation.
Argon (and the other noble gases) is separated by fractional distillation of liquid air.
Argon is separated from air by a process called cryogenic distillation. Air is cooled to very low temperatures to liquefy and then slowly heated up. As different components of air have different boiling points, argon is separated from other gases based on its boiling point which is lower than that of nitrogen and oxygen.
Air components are separated by criogenic distillation.
The best process for the separation of components of air is fractional distillation of air. The process includes the liquefaction of air first and then distillation of various fractions on the basis of different boiling points. By using this process, all the components of air can be separated out.
A homogeneous mixture of gases (air) can be separated by fractional liquefaction. The mixture is gradually cooled, with the gases being separated by differences in boiling point.
Air components are separated by criogenic distillation.
Oh yes, dust can be filtered out of air. It is done all the time.
The method of obtaining nitrogen from air was developed by Dr Carl von Linde.
