A thermodynamic state function, entropy S, can be defined as đQ AS = S-S; T where i stands for initial state and f stands for final state. = - - (a) State the principle of increasing entropy. (b) Two equal quantities of water, of mass m and at temperatures T1 and T2, are adiabatically mixed together, the pressure remaining constant. Show that the entropy change of the universe is: (Tz + T₂ AS = 2mcpln 12/TT₂ = where cp is the specific heat of water at constant pressure. (10 Show that AS 2 0. (Hint: (a - b)2 2 0 for any real a and b.) (7
