Explanation:

1. Ice in a glass of water

Heat flows from a warmer object to a cooler one. Water is warmer than ice, so heat moves from water to ice.

Hot soup has higher temperature than the metal spoon. Heat transfers from the warmer soup to the cooler spoon.

Your hand (body) is warmer than the cell phone (assuming phone is at room temp or cooler). Heat flows from hand to phone.

Answer:

First box: Water, Second box: Ice

2. Metal spoon in a bowl of hot soup
