) bottles are filled with water. One bottle is left uncovered, while the other is sealed with a cap. After some time, you observe that the water level in the uncovered bottle has decreased, while the water level in the sealed bottle remains the same.

This phenomenon can be explained by the process of evaporation. When a liquid is left uncovered, its molecules at the surface gain enough energy from the surroundings to escape into the surrounding air as vapors. This process is called evaporation.

In the case of the uncovered bottle, the water molecules on the surface continuously evaporate, causing the water level to decrease over time. However, in the sealed bottle, the cap prevents the water molecules from escaping into the surrounding air, so there is no evaporation occurring. As a result, the water level remains the same in the sealed bottle.

Overall, the difference in water level between the uncovered and sealed bottles is due to the evaporation process, which only occurs in the uncovered bottle.
