When liquid water evaporates it becomes a gas. The volume increases as gas molecules move farther apart.A. If volume increases due to evaporation, what happens to the density of the water?

It decreases (D = M/V)

B. Explain why clouds form over warm ocean waters:

Water evaporates as it is heated. It has a lower density (a gas), so it rises. Once it cools to its dew point the vapor condenses to form cloud droplets.
