One of them is mixing of two or more different substances, occasioned by bringing them together by removing a wall that separates them, keeping the temperature and pressure constant. The mixing is accompanied by the entropy of mixing.

WebWe can also derive an expression for the change in entropy as a function of constant pressure heat capacity, C P. To start, we need to change from internal energy, U, to enthalpy, H: H = U + P V d H = d U + d ( P V) = d U + P d V + V d P For reversible processes: d H = d U + P d V + V d P = T d S − P d V + P d V + V P = T d S + V d P WebEntropy increases with mass F2 ( g) = 203 J/mol·K Cl2 ( g) = 224 J/mol·K Br2 ( g) = 245 J/mol·K I2 ( g) = 261 J/mol·K 2.
