c. 0.5 g/ml
d. 1 g/ml

Question 4

Step1: Recall density and layering

From the diagram, Liquid A is above Liquid B (water, density \(1\) g/mL), so Liquid A is less dense than water? Wait, no—wait, the layers: if B is water (middle), C is at the bottom, A at the top. Wait, density determines layering: more dense sinks. So C is most dense (sinks to bottom), B (water) in middle, A least dense (floats on top). Wait, but question 4: If B is water (density \(1\) g/mL), what's density of A? Since A is above B, A must be less dense than B? Wait no, wait the options: A is 2, B 1.5, C 0.5, D 1. Wait, no—wait, maybe I got the layers wrong. Wait, the container: C is at the bottom, B in the middle, A at the top? Wait, no, the labels: A is a square, B is a square, C is a square. Wait, the diagram (though blurry) shows C at the bottom, B in the middle, A at the top? Wait, no, maybe the layers: the liquid with highest density is at the bottom (C), then B (water), then A (top). So density order: \(
ho_C >
ho_B (1 \text{ g/mL}) >
ho_A \). Wait, but the options for A's density: A. 2 (higher than 1), B. 1.5 (higher than 1), C. 0.5 (lower than 1), D. 1 (same as B). Since A is above B (water), A must be less dense than B (1 g/mL). So only option C (0.5) is less than 1. Wait, but wait—maybe I mixed up. Wait, if B is water (middle), then above B (less dense) is A, below B (more dense) is C. So \(
ho_A <
ho_B = 1 <
ho_C \). So A's density must be less than 1. So option C (0.5) is correct. Wait, but let's check the options again. The options are A. 2, B. 1.5, C. 0.5, D. 1. So since A is above B (water, 1 g/mL), A's density must be less than 1. So only C is less than 1. So that's the answer.

Step1: Recall density and layering

Density determines the vertical position of liquids: more dense liquids sink to the bottom. From the diagram (C at bottom, B in middle, A at top), the liquid at the bottom (C) has the greatest density because it sinks the most. So the liquid with greatest density is C.

Step1: Recall density and layering

Liquids with lower density float on top. From the diagram (A at top, B in middle, C at bottom), the liquid at the top (A) has the least density because it floats the highest. So the liquid with least density is A.

Answer:

C. 0.5 g/mL
