  1. List 3 physical properties of water. Answer the following questions in pairs in writing: • Define these three physical properties. • Differentiate among these properties. • Explain the chemical background that causes these properties. • Identify the biological phenomena that are caused by these properties.

  2. The following questions should be answered individually: • Draw five water molecules and connect them to each other. Label the bonds involved in forming these molecules. • Why is water polar? • Why is water transparent? • Define viscosity and explain why water has a low viscosity. Identify the biological phenomena that results because ofthe low viscosity of water

  3. What chemical property is responsible for the high surface tension of water? Identify the biological importance of the high surface tension of water. • Identify a specific acid. Describe the characteristics of acids. • Identify a specific base. Describe the characteristics of bases. • Define what an indicator is and give an example. • Define what a buffer is and give a reason why they are important in living things.
