I’ve seen similar water droplets on cold beverage cans, especially during summer. In bathrooms after a hot shower, condensation forms on mirrors and tiles. Even on plants, dew appears in the early morning.
The water droplets on the outer surface of the glass are due to condensation. The cold temperature of the glass causes moisture in the air to cool and change from vapor to liquid, forming droplets.
The disappearance of water from puddles is due to both seeping into the ground and evaporation. The soil absorbs moisture, while sunlight and warmth cause water to evaporate, reducing puddle size effectively.
Other examples of evaporation include drying clothes on a line, puddles disappearing after rain, water in a pot boiling, and sweat evaporating from our skin. Each illustrates how heat converts liquid to vapor in different contexts.
