Worked Solution

Step 1: Evaporation happens when water gains heat and turns into water vapour. Step 2: Condensation happens when water vapour loses heat and turns into water droplets. Step 3: Therefore, evaporation is heat gain, and condensation is heat loss.

Correct answer: Heat Gain: Evaporation; Heat Loss: Condensation
