Answer to Question 1

There is condensation forming on the outside of the glass. This is due to the temperature difference between the atmosphere and the beveragebecause the drink is cooler than the air, the atmosphere immediately around the glass is cooled and reaches atmospheric saturation. This causes moisture from the atmosphere to condense on the solid surface of the glass.

Answer to Question 2

The condensation nuclei are particles that allow microscopic cloud droplets to form in suspension in the atmosphere. Once condensation takes place, initial cloud droplet growth rate is rapid.
