Water does not come from a bowl due to condensation but the surrounding air. Water vapor is the gaseous form of water that exists in air below the boiling point of water. Since it takes a lot of energy to turn water into vapor, the molecules in the air have higher thermal energy than the molecules in the cold glass. As a result, when the water molecules collide with the glass, they transfer most of their thermal energy to the glass. The cold water molecules form water droplets on the glass in the water. It is called condensation. This process will also happen on window sills when the outside air is cold and the room air is hot and humid.
