Degrees of Freedom/Sensitivity The main Feed This is the inlet stream to the unit in which the substance to be extracted is originally dissolved. The input streams consist of a solution feed at When a solid is heated to its melting point, it changes into a liquid. When a liquid is cooled to its freezing point, it turns into a solid. Gases turn into liquids if they are cooled down. This is called condensation. Liquids turn into gases if they are heated to their boiling point. We have separately trained faculty to ensure that every difficult concept is a bed of roses for our There is a net transfer of one or more species from one liquid into another liquid phase, generally from aqueous to The distribution of a solute between two phases is an equilibrium condition described by partition theory.
