Base your answer to the question on the diagram above, which shows insulated styrofoam cups of water connected by an aluminum bar. The thermometers show the temperatures of the cups A and B at the beginning of a heat flow experiment. 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.
