Extracted text: Fig 1. Experiment set-up Activity Lowering 3: Vapor-Pressure Materials: Water Solvent Solution Aqueous solution (a) Two glasses One sealed enclosed container Procedure: 1. Get two glasses placed side by side in a sealed enclosed container. One glass contains pure water, the other an equal volume of an aqueous solution of sugar. Take note of the volume Solution b) of water and sugar solution. (See figure 1.a) 2. Leave the set-up until the next day. Gradually measure the volume of the sugar solution and that of the pure water. Is there any change in their original volume? (See figure 1.b) Analysis: 1. What can you infer about the change in volume of the sugar solution and that of pure water? 2. What has caused this change in volume of the sugar solution and that of pure water?
