sep ask questions the process of evaporation has a different outcome in an open system versus a closed system. what happens to the water level in a closed water bottle compared to an open water bottle if you set them both out in the sun?
Answer
Explanation:
Step1: Evaporation in open system
In an open - water bottle, water molecules gain enough energy from the sun's heat to change from the liquid phase to the gas phase (water vapor) and escape into the atmosphere. So the water level in the open water bottle decreases over time.
Step2: Evaporation in closed system
In a closed water bottle, water molecules also gain energy from the sun's heat and some of them change to the gas phase. But since the bottle is closed, the water vapor cannot escape. Instead, it accumulates inside the bottle. After a while, an equilibrium is reached where the rate of evaporation equals the rate of condensation. So the overall water level in the closed water bottle remains approximately the same.
Answer:
The water level in the open water bottle decreases, while the water level in the closed water bottle remains approximately the same.
