When the ice cream is placed on a metal surface that is at a room temperature of 25 degrees Celsius, heat will be transferred from the metal surface to the ice cream. This is because the metal surface is at a higher temperature than the ice cream, which is colder. As a result, the ice cream will absorb heat from the metal surface, causing it to melt.
Therefore, the correct response is:
Heat is transferred from the metal surface to the ice cream, and the ice cream melts.
