A 1.20 kg iron cube at 343 K is placed in contact with olive oilat 283 K in a thermally insulated container. The specific heat ofiron and oil is 450 J/(kg.K) and 1970 J/(kg.K), respectively. Bothmatters reach thermal equilibrium at 301.8 K, and there is no phasechange and no chemical process in this example. (a) Find the amountof heat transfer for (i) the iron cube, and (ii) the olive oil. (b)Find the total change in entropy of this entire iron-oil system.Does your result validate the 2nd Law of Thermodynamics?
