Passage VI
The pressure,
, exerted by a liquid varies with the depth, D, below the surface of the liquid and with the liquid’s density, ρ. If a tank of liquid is open to the atmosphere, the total pressure,
, at D equalsat D plus the atmospheric pressure,
.
Table 1 lists ρ, in kilograms per cubic meter (kg/m³), for 4 liquids at 25℃.
Figure 1 shows, for D = 10 m, a graph of (in kilo-pascals, kPa) versus ρ (1 kPa = 
Pa =newtons/㎡). Figure 2 shows a graph of versus D and a graph ofversus D for 25℃ water in a tank that was open to the atmosphere on a particular day.
30. What is the correct ranking of the liquids listed in Table 1, from the liquid with the least density at 25℃ to the liquid with the greatest density at 25℃?
Your Answer is
Correct Answer is J
Explanation
Sorting questions, density from small to large. See table 1, Ethanol 78
