Perhaps you recall that when table salt, NaCl, is added towater, the freezing point of water is lowered. Consider a systemcomposed of a mixture of 2.5kg of ice and 50g of liquid water and asmall, separate container of finely powdered salt. This physicalsystem is contained in a fully insulated container that preventsall thermal interactions with the environment. Both the salt andthe ice-water mixture are initially at the freezing point of water,0 °C. The salt is then added to the ice-water mixture, and thesystem of ice-water and salt is allowed to come to thermalequilibrium. The final equilibrium temperature is less than 0°C.
Use the Energy-Interaction Model Preview the document to predictif there will be a greater or lesser amount of ice in the finalequilibrium state than in the initial state before the salt wasadded. Your explanation should include a complete Energy-SystemDiagram. [The simplest way to model this physical system is withone thermal energy system for everything and one bond energysystem, i.e., in terms of the model, it is not useful todistinguish between the various chemical components in order toanswer this particular question.]
