Question

When the bottle was open, water will rise up through the straw to the same height as the water inside the bottle. Why?

Answer 1

Answer:

Air pressure, water pressure, gravity

Explanation:

since air from above is pushing down on the water, some parts of the water go inside the straw, also water pressure acts the same.

However, due to gravity the water downt flow out of the straw making it stable at an equal level of water.
