Why is mass transfer a major factor in separation processes?

Expert Solution

Separation is the process of separating into it's individual components from a mixture or collection of specified components from a mixture and transfer into another pure substance or mixture.

This separation can be done by transfer of mass of specified component from one region to another region.

Without mass transfer separation can't be takes place.

This mass transfer is defined as, "Net moment of molecules in the mixture from a region of higher concentration to lower concentration by virtue of thermal energy of the molecules".

Separation should be done by transfer of mass only. A driving force should be need for mass transfer. Concentration difference is the driving force in single phase operation and difference in chemical potential is the driving force in multiple phase system.

Causes for separation is either difference in solubility or the difference in volatility (Vapor pressure or boiling point).

In a double-slit experiment, if the slit separation is increased by a factor of two, what happens to the interference pattern shown on the screen? What happens if the wavelength is halved? What happens if the distance to the screen is double? Two small forward-facing speakers are 2.50 m apart. They are both emitting, in phase with each other, a sound of frequency 1100 Hz in a room where the speed of sound is 344 m/s. A woman is standing...
