Every gram of ice surrounding the soft drink extracts out 336J of heat energy from it and the temperature of surrounding the soft drink remains at 0°C. However, in case of cold water, it will extract out only 4.2J of heat energy per gram.
Furthermore, the temperature of surrounding water starts rising.
Thus, soft - drink bottle cools better in case of ice.
