Question

People float in saltwater more easily than they do in freshwater. Likewise, some objects that sink in freshwater will float in saltwater. Based on these facts, what can be in erred about the density of saltwater and the density of freshwater? Explain the conclusion. When ice melts in a glass of regular soda without being disturbed, the following observations can be made: (1) the ice floats in the soda. (2) water from melted ice remains above the soda, and (3) the ice floats in the water. What can be inferred about the relative densities of ice. water, and regular soda? A crude on spill from a deep-water drilling platform is always possible. The density of crude oil ranges from 0.8 g/cm^3 to 0.9 g/cm^3. How might the density of crude oil affect its impact on wildlife, both aquatic and terrestrial? How might its density affect clean-up operations? How might the density of crude oil affect potential fires?

Explanation / Answer

****

Since objects floats on salt water but not on fresh water, it is concluded that salt water is more denser than fresh water.

Because, less denser objects can float on the surface of more denser objects.

****

Based on the given information, the density order of,

Regualr soda > water > ice.

Becuase water coming from ice floats on soda and inturn ice floats on water.
