Question

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

Answer 1

The air.

The cold glass chills the air that touches it, causing it to shed moisture, which condenses on the glass.

Answer 2

The water that condenses on the outside of a cold glass comes from the humidity in the air.

Answer 3

it comes from the water vapor in the air. The warmer temperatures surrounding the glass and the lower temperatures in the glass cause a drop in dew point, or the temperature at which water in the air condensates and falls as dew. The drink cools the air to a point were it can't keep the water in a gaseous form, and it forms visible water droplets on your glass.

Answer 4

the air.

just like rain.

or fog.
