Anna pours herself some room-temperature soda from a bottle and adds four ice cubes. In a few minutes the ice cubes are smaller and the soda is much colder. Which of the following best explains the change in temperature of the soda?
A. Heat flowed from the soda to the ice cube and caused it to partially melt.
B. Coldness flowed from the ice cube to the soda, making the soda cooler.
C. The cold water from the melting ice went into the soda, replacing the warmer water that was in the soda
D. The water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.
