Answer 1

Condensation forms on the outside of a glass of ice water mainly because of warm, moist air coming in contact with the cold glass.

Step-by-step explanation:

Condensation forms on the outside of a glass of ice water on a humid day mainly because of the warm, moist air outside the room coming in contact with the cold pane of glass. The temperature of the nearby air is reduced to below the dew point, causing the water vapor in the air to cool and condense into liquid water on the cold glass. This is similar to how condensation forms on the outside of a cold beverage glass. When gaseous water is cooled, the attractions between water molecules are capable of holding them together, causing the water vapor to condense into liquid water on the glass.
