Question

1. over the next 15 minutes, which changes would most likely occur? the temperature in cup a will decrease and the temperature in cup b will increase. the temperature in cup a will decrease and the temperature in cup b will decrease. the temperature in cup a will increase and the temperature in cup b will increase. the temperature in cup a will increase and the temperature in cup b will decrease.

Explanation:

In heat transfer, heat flows from a higher - temperature region to a lower - temperature region. Cup A has boiling water (100°C), and Cup B has room - temperature water (20°C). Through the aluminum bar (a good conductor of heat), heat will transfer from Cup A to Cup B. So, the temperature of Cup A (higher - temp source) will decrease as it loses heat, and the temperature of Cup B (lower - temp receiver) will increase as it gains heat.

Answer:

The temperature in cup A will decrease and the temperature in cup B will increase. (The option with this description, likely the fourth option in the list: "The temperature in cup A will decrease and the temperature in cup B will increase.")
