The graph shows the effect of increasing the side length of agar cubes on the surface area and the volume of the cubes. [Figure 17.1] Which row correctly identifies line 1, line 2 and the effect of increasing side length on the surface area: volume ratio of the cubes?

This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.

Aline 1: surface area, line 2: volume, surface area: volume ratio: decreases

Bline 1: surface area, line 2: volume, surface area: volume ratio: increases

Cline 1: volume, line 2: surface area, surface area: volume ratio: decreases

Dline 1: volume, line 2: surface area, surface area: volume ratio: increases

✓ Correct answer

C: line 1: volume, line 2: surface area, surface area: volume ratio: decreases
