5. Discuss the environmental consequences if ice were denser than water. 6. How does the vapor pressure of water at a given temperature compare to that of other
substances with similar molar masses? Explain. How does this affect the rate of evaporation of
bodies of water?
7. Use the table above (Table above) to answer the following.
a. What is the volume of 100.0 g of water at 100°C?
b. What is the volume of 100.0 g of water at 4°C?
c. What is the volume of 100.0 g of water at 0°C?
d. What is the volume of 100.0 g of ice at 0°C?
8. A completely full bottle of boiling water is placed in the freezer. Discuss what happens as the
water cools and eventually freezes.
9. Explain which property of water is responsible for each of the following phenomena.
a. An asphalt road breaks apart as water seeps into small cracks and freezes.
b. A bottle of gasoline evaporates more quickly than a bottle of water.
c. Water forms nearly spherical drops as it slowly drips out of a faucet

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
