Sieving or winnowing? Why? 6. What are the different properties that you would consider to
separate a solid-solid mixture?
7. Two students are trying to separate 50 g of mixture of sand and
iron splinters by using a bar magnet. Kinley Wangmo spreads the
mixture on a sheet of paper. Wangchuk tries with a heap of the
mixture on a sheet of paper. Both use bar magnets to remove the
iron splinter from the mixture.

The small bags of silica gel you often see in a new shoe box are placed there to control humidity. despite its name, silica gel is a solid. it is a chemically inert, highly porous, amorphous form of sio2. because water vapor readily adsorbs onto the surface of silica gel, it acts as a desiccant. despite not knowing mechanistic details of the adsorption of water onto silica gel, from the information provided you should be able to make an educated guess about the thermodynamic characteristics of the process. predict the signs for δg, δh, and δs for the adsorption of water.
