Which one is colder bottles or can?

Cans are generally colder than bottles when both are taken from the same environment because aluminum, which is used for cans, conducts heat more efficiently than glass or plastic. As a result, cans cool down more quickly in a refrigerator or cooler. Additionally, the larger surface area of a can allows for more rapid heat exchange. However, once out of the cooling environment, the temperature of both will equalize with the surrounding air over time.
