Worked Solution

Step 1: Melting requires the ice to gain heat from its surroundings. Step [2-9]: Metals are good conductors of heat compared to wood, ceramic, or plastic. Step [2-9]: The metal plate transfers heat from the air to the ice faster, causing it to melt first.

Correct answer: Ice on the metal plate
