5. If the 5 fastest runners on the track team left, what would happen to the average speed of the remaining runners? How does this compare to evaporative cooling when you sweat? 6. Describe the property of water being shown here. How do water's hydrogen bonds contribute to this property. 7. Ice floats on liquid water because it is less dense. Explain why ice is less dense and how this relates to hydrogen bonds. WHY DOES ICE FLOAT? Fod teachoo
8. This graph represents the density by temperature curve of water and of a "typical" liquid. Explain in your own words how the density of water changes with temperature compared to a "typical" liquid and why it differs. What happens to the density of water right at 0 deg C? (the red line is water, the green line is a "typical" liquid) Liquid water Density (g/cm²) 1.0010 1.0000 0.9990 0.9980 0.9170 Ice 0.9160 "C: -2 0 (F): (28.4) (32) d 1.0000 0.9999 density density C At 0°C, ice forms and density decreases 9. Besides the melting of ice, how will rising temperatures cause sea level rise? Use information provided in the graph above to answer the question.

10. "Navy coffee" is where the coffee is brewed strong and a bit of salt is added. Explain or draw how the water molecules in the coffee would orient themselves to form hydration shells around the salt ions (Na+ and Cl-).
