Worked Solution

Step 1: Process A shows water bodies turning into water vapour. This is evaporation, which requires heat gain. Step 2: Process B shows water vapour forming clouds. This is condensation, which requires heat loss. Step 3: Match Process A (Heat Gain) and Process B (Heat Loss).

Correct answer: Process A: Heat Gain, Process B: Heat Loss
