Response Details:
When water vapour condense on the walls of the beverage, some of  the heat will be taken from the beverage bottle so the bottle gets chilled.

Response Details:
 when u remove a cold beverage from a refrigerator in a humid room water vapour will condence on the walls of the container .,because there is temperature difference between refrigirator and outside. According to the laws of thermodynamics, heat flows from high temperature to low temperature body.
 Yes, condensation has effect on the temperature of the beverage. The temperature of the beverage goes on increasing its temperature till it reaches the room temperature if it is left in the room

Response Details:

I believe the question refers to the actual condensation process and what heat flow is occuring in that process.  Condensation is the reverse of evaporation.  Evaporation is endothermic while condensation is exothermic.  Oh, gosh, condensation is releasing energy then.  If that is the case, energy is being release onto the can's surface and ultimately being absorbed by the contents inside.  The beverage's temperature will of course increase.  The T increase is due to both the condensation process and the fact the heat is flowing from the warmer room to the colder container.
Spending precious time on a problem that results in a rating of "not helpful" or "somewhat helpful" is deemed a wasted effort. With certainty, I'll be sure not to provide assistance in that direction again.
