Why does coke sweat when brought out of the frigde and left to settle down?

Coke sweats due to condensation. When a cold can of Coke is removed from the fridge and exposed to warmer air, the temperature of the can decreases, causing the moisture in the warmer air to cool rapidly. This cooled air loses its ability to hold water vapor, resulting in water droplets forming on the surface of the can. This phenomenon is similar to how dew forms on grass in the morning.
