Passage V

Density is defined as the mass of a substance divided by its volume:

Table 1 lists the phases and the densities, in grams per cubic centimeter (g/cm3), of various pure substances at 25°C and 1 atmosphere (atm) of pressure.

Figure 1 shows how the density of liquid water changes with temperature.

Figure 2 shows how the density of solid water changes with temperature.

28. Equal amounts of ethyl ether, mercury, and water (density = 0.9971 g/cm3) at 25°C are poured into a single beaker. Three distinct layers of liquid form in the beaker. Based on the data in Table 1, which of the following diagrams represents the order, from top to bottom, of the liquids in the beaker?

Answer and Explanation

Your Answer is

Correct Answer is F

Explanation

General knowledge questions.

Those with high density sink to the bottom, and those with low density float up. Looking at table 1, the density of mercury is 13.59 g/cm3, the density of ethyl ether is 0.71 g/cm3, and the density of water is 0.9971 g/cm 3, so ethyl ether has the lowest density and is on the top layer; mercury has the highest density and is on the bottom layer.
