2009-09-19· A physical separation is a separation (i.e. one solution becoming two or more solutions) based upon the physical properties of the solutions being separated. For example, if the two solutions are two oils with different specific volumes, a physical separation is letting those two oil settle and separate, with two streams (one from the top, one from the bottom). A physical properties can be ...
