Worked Solution

Step 1: Identify the source of water (water vapour in the surrounding air). Step 2: Identify the heat change (vapour loses heat to the cold can). Step 3: Identify the process (condensation from gas to liquid).

Correct answer: Water vapour from the air lost heat to the cold surface and condensed.
