Problem: Question relates to equations of state. Cabelling (see Lec. 6 or look up on Wikipedia) is a process where mixing of two water masses of the same density can lead to the resulting watermass being denser than before, and is important for deep water formation.
(a) Provide a pictorial argument as to why cabbelling cannot occur with a linear equation of state. Need Assignment Help?
(b) Sketch out a hypothetical case of a nonlinear equation of state where you can get reverse /anti- cabelling, i.e., mixing of two watermasses of the same density leads to a resulting watermass that is less dense.
