In each of the following situations, the pressure at a specific point inside the water bottle will increase.
1. Near the bottom of the bottle: As the water falls, the distance between the bottom of the bottle and the specific point near the bottom decreases. According to Pascal's law, the pressure in a fluid increases with depth. Therefore, the pressure near the bottom of the bottle will increase.
2. At the surface of the liquid: When the water falls and the bottle is flipped upside-down, the liquid will exert a force on the surface of the water bottle due to gravity. This force will compress the air inside the bottle, leading to an increase in pressure at the surface of the liquid.
Overall, the pressure inside the closed water bottle will increase as the liquid falls due to the change in depth and the compression of air at the surface.
