Worked Solution

Step 1: In Setup A (hot water), warm water vapour rises and comes into contact with the cooler inner surface of the glass, losing heat and condensing there. Step 2: In Setup B (ice water), warm water vapour from the surrounding air comes into contact with the cooler outer surface of the glass, losing heat and condensing there.

Correct answer: Inner surface of Glass A and outer surface of Glass B
