1. A cup of coffee is made in the morming by pouring boiling water over ground-up coffee beans held in a special piece of paper and by collecting the brown liquid that comes through. Which techniques of the five described in the Introduction section is used in the preparation of the drink? 2. A tablespoon of sugar is added to the cup of coffee and the solid disappears. What makes up the “cup of coffee" now? Is this a mixture? 3. What is taking place during the process of sublimation? How is this process different from evaporation?
