Question

dec. 2 thermal energy day 1 notes practice
what happens to the temperature of the hand and ice cube over time?
heat transfer
image of a hand holding an ice cube, labeled warm (hand) and cool (ice cube)

• they become the same temperature
• the hand stays warm
• the ice cube stays cold
• they never change temperature

Explanation:

This question is about heat transfer, a concept in Physics (a subfield of Natural Science). When a warm hand holds a cold ice cube, heat transfers from the hand (higher temperature) to the ice cube (lower temperature) until thermal equilibrium is reached, meaning they become the same temperature. The other options are incorrect: the hand will cool down (so it doesn't stay warm), the ice cube will warm up (so it doesn't stay cold), and their temperatures do change as heat transfers.

Answer:

A. They become the same temperature
