Worked Solution
Step 1: Both setups have the same amount of water and are exposed to the same heat source (hot sun).
Step 2: Setup B has a wider opening, meaning the water has a larger exposed surface area.
Step 3: A larger exposed surface area increases the rate of evaporation.
Step 4: Therefore, more water will evaporate from Setup B, leaving less water remaining.
Correct answer: Setup B, because it has a larger exposed surface area.
