Why is there liquid on the bottom of my cup?
When water vapor in the air comes into contact with something cool, such as the outside of a cold glass of lemonade, its molecules slow down and get closer together. When that happens, the gaseous water vapor turns back into liquid water droplets. That’s condensation!.
How does water get under a cup?
Condensation on Glass When the hot air comes in contact with the cold glass, heat is transferred from the hot air to the cold glass. The loss of heat in the surrounding air causes the water vapor by the glass to lose energy. Once energy is lost, the water vapor condenses into liquid on the glass.
What are the cons of using ceramic cups?
Ceramic mugs can crack, break, or chip if not handled carefully. Large ceramic coffee mugs may not keep your beverages hot for very long.
Are ceramic coffee mugs safe?
If ceramics are baked for long enough at hot enough temperatures, they may still be safe, but if not, the lead can leach into food and cause lead poisoning.

Where does the water at the bottom of the watch glass come from?

Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
