The droplets of water observed around a bottle of milk taken out of the refrigerator is due to the fact that the?
water vapour in the air around the bottle gains some energy from the bottle
temperature of the milk drops as it loses heat into the surroundings
saturated vapour pressure of the milk is equal to the atmospheric pressure
water vapour in the air around the bottle loses some of its energy to the bottle
คำอธิบาย
When a cold milk bottle is taken out from the refrigerator, the water vapor in the air around the bottle comes in contact with the cold surface of the bottle and gets condensed.
