19. We consider a three-step reversible process as follows: the supercooled water drop (of mass m ) starts at state 1 ( T 1 = 268 K), moves on to state 2 (still in liquid form but at T 2 = 273 K), freezes to state 3 ( T 3 = T 2 ), and then cools down to state 4 (in solid form, with T 4 = T 1 ). The change in entropy for each of the stages is given as follows: Δ S 12 = mc w ln ( T 2 / T 1 ), Δ S 23 = mL F / T 2 , Δ
