Question

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?
heat flowed from the soda to the ice cube and caused it to partially melt.
coldness flowed from the ice cube to the soda, making the soda colder.
the cold water from the melting ice went into the soda, replacing the warmer water that was in the soda.
the water from the melting ice makes the soda more dilute, and the lower concentration makes the temperature lower.

Explanation:

Heat transfer occurs from warmer objects to cooler ones. The soda is warmer than the ice cubes, so heat moves from the soda to the ice, causing the ice to melt and the soda to cool down. Concepts like "coldness flowing" are incorrect, and dilution does not cause the temperature drop.

Answer:

A. Heat flowed from the soda to the ice cube and caused it to partially melt.
