1. Solid to Vapor (LAB #1) BOBBY MOUNSATH MARIAH JOHNSON AMBER PARAMORE

2. Purpose  To observe the sublimation of air freshner

3. Materials  Small pieces of an air freshener  Small shallow container  2 clear 8 oz. Plastic cups  Hot tap water  Ice  3 thick cardboard strips

4. Procedures  1. Place a few pieces of air freshener in one of the cups  2. Bend cardboard strips and put them over the rim of the cup that contains the air freshener  3. Put the second cup inside the first cup. The second cup shouldn't touch the air freshener  4. Fill the top cup with ice, don't get any ice or water into the bottom cup  5. Fill the shallow container about 1/3 full with hot tap water  6. Carefully place your sublimator in the hot tap water. Observe what happens.

5. (Data/Results) Data Table #1: Shown on the Containers

6. Data Table #2: Evaporation of Materials

7. Conclusion/Analysis  The first chart shows what was observed in the containers, which was the shallow container, the bottom cup, and the top cup. The shallow container showed evaporation happening above the water. The bottom cup showed evaporation on the outside. And the top cup showed no sublimation. The ice in the top cup partially melted, due to the hot tap waters temperature, and the air freshener melted, but not completely.

8. Conclusion/Analysis Questions  1. Sublimation- Process when a solid turns to vapor  2. The water in the shallow container at room temperature would have no effect on the ice or air freshener. If the water were boiling the ice and air freshener would melt very quickly, and the plastic cups would become effected to, which would ruin the whole lab experiment.  3. Just like distillation, the different components of a mixture have different boiling and sublimation levels. If a mixture is heated up, the component that takes the least amount of energy to undergo sublimation will be evaporated out first, and the other component remains there in its original state.
