Best Answer

The glass is not actually "sweating." What you are seeing is condensation of water molecules from the air onto the glass's surface. Because the water in the glass has less energy than the water in the air (it's cooler), energy from the water molecules in the warmer air is given up to warm the cooler water in the glass. This loss of energy results in the air water molecules' inability to break the number of hydrogen bonds between themselves necessary to remain in the gas phase and ultimately the condensation of water onto the outside of the glass surface.

Where does the water come from on the outside of a cold glass?

It is water that condenses out of the air. When moisture-laden warmer air comes into contact with the cold surface of the glass, the glass absorbs heat from the air, and if conditions are right it absorbs the heat that has maintained the water as vapor. When this energy is absorbed by the glass, the vapor condenses into liquid water. This general idea comes into play when you notice the mugginess of a humid day. The reason sweat gathers on your skin is because the evaporation process that usually happens is slowed down by the amount of moisture already in the air. If the air is saturated with water vapor, your sweat doesn't evaporate. When your sweat does evaporate, it's because the air absorbs energy from the sweat, which is why we experience a cooling effect.
