Does a plastic bottle of fresh water sink or float in the ocean? Why?
A) Sinks; The combined density of the plastic bottle plus the fresh water inside is greater than the density of the ocean water.
B) Floats; The bottle filled with fresh water floats in ocean water because it is less dense than the ocean water.
C) Floats then sinks; The bottle filled with fresh water floats in ocean water until the fresh water reaches the same temperature as the ocean water, at which point it sinks.
D) Sinks slightly; The added density of the plastic bottle will cause the bottle to sink slightly. It would most likely sink less than a foot where the density of the ocean water would be equal to or greater than the bottle of fresh water.
