1. From the hot water faucet, obtain about 800ml of 30°C water in a 1000 ml beaker and place the beaker on a sheet of plain white paper.
2. In a 250 ml beaker add approximately 150 ml of water and enough red food coloring to produce a deep red color. The food coloring will act as a tracer to enable you to observe the water.
3. Add sufficient ice to the red water in the 250 ml beaker to bring the temperature of the water to 4°C.
4. With a 10ml pipette, gently add approximately 10ml of the red 4°C water to the bottom of the 1000ml beaker of 30°C water.
5. Observe from the side of the beaker. What do you observe happening to the 4°C water?
6. Explain in detail how the behavior of water noted above relates to it's change in temperature and density.
7. Gently place the ice cube on the surface of the water in the 1000 ml beaker and observe the melting process and any water movement that occurs.
8. Why is the ice floating?
9. Describe the movement of the blue ice as it melts.
10. Explain in detail how the behavior of water noted in (#8, 9) relates to it's change in temperature and density.
12. Describe the final condition of the water in the beaker after several minutes.
