This is condensation.

It's called "condensation"...The glass gets colder than the dewpoint temperature of the air (temperature at which saturation occurs and water vapor turns into liquid water) and therefore water drops form on the cold glass.
condensation occours.
When you have a glass of cold water from the fridge that you take outside, because it's hotter outside, little drops of water will form on the glass.
condensation, where water vapor in the air comes into contact with the cold glass surface and changes from a gas to a liquid.
The water comes from the air. Air as it exists under normal conditions in the atmosphere contains some small fraction of water vapor. When the glass is cold the water molecules strike the glass and cool off, becoming liquid.
Water vapors appear outside a glass containing ice or chilled water due to condensation. The cold surface of the glass cools the air around it, causing the moisture in the warm air to lose energy and change from vapor to liquid. This results in tiny water droplets forming on the outside of the glass, which is often seen as "sweating." The process is similar to how dew forms on grass in the morning when the temperature drops.
