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.

27. Which of the following hypotheses about the relationship between the temperature and the density of a solid is best supported by the data in Figure 2 ? As the temperature of a solid increases, the density of the solid:

Answer and Explanation

Your Answer is

Correct Answer is B

Explanation

Look at figure 2, as the abscissa temperature rises, the ordinate density decreases
