Yes, we can conclude that the water collected outside the tumbler is solely due to condensation. The cool surface of the tumbler causes moisture from the air to condense, forming droplets on the exterior.

Yes, we can conclude that water is not seeping through the wall of the tumbler. The closed system, with the steel plate, prevents any water from escaping or entering, maintaining the total mass.
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.
Water disappears due to evaporation, where heat transforms liquid into vapor. Plants also absorb water for growth, releasing moisture into the air through transpiration, contributing to the overall movement of water in the environment.
I’ve seen water disappear in many places, like on roads after rain or in my garden when plants absorb moisture. Evaporation also plays a role, especially on hot days, reducing visible water quickly.
The soil likely absorbed the water from the puddles. When soil is saturated, it can take in excess moisture, which helps reduce standing water and keeps the playground drier and more enjoyable.
If rain fails to replenish water sources, the entire ecosystem suffers, leading to reduced freshwater input into rivers and lakes. Eventually, even oceans can feel the impact, as evaporation exceeds replenishment, threatening marine life.
