Worked Solution

Step 1: Her hand is warmer than the ice cube. Step 2: Heat always flows from a warmer object to a cooler object. Step 3: Her hand loses heat to the ice (making her hand feel cold), and the ice gains heat (causing it to melt).

Correct answer: Heat travelled from her hand to the ice.
