You are a server in a restaurant, always interested in going the extra mile for your customers. Patrick, a regular customer in your section, has ordered sweet iced tea and has an appointment in 10 minutes, so he must drink quickly then leave. The kitchen staff makes only unsweetened tea, but there are sugar packets on the tables. What should you do for Patrick to provide the best sweet tea, and
what general principle of diffusion does this illustrate? (Hint: Will sugar dissolve quickly in an iced drink?)
What will be an ideal response?
Make sugar syrup for Patrick by heating a small amount of water with a generous amount of sugar. The sugar diffuses through the water as it dissolves, and this will occur much quicker in warm water (diffusion rate increases with increasing temperature). Then add the syrup to his iced tea and serve.
