What happens to water vapor when it cools on a glass of ice tea and becomes liquid?

When water vapor cools on a glass of ice tea and becomes liquid, the process is known as condensation. Condensation occurs when water vapor turns back into liquid water. This happens when the water vapor comes into contact with a surface that is cooler than the dew point of the air, which is the temperature at which the air becomes saturated with water vapor and condensation begins to form. In this case, the glass of ice tea is colder than the dew point of the air, so the water vapor in the air condenses on the surface of the glass and forms droplets of liquid water.
