physics education resources, simulations, demonstrations and videos by a Singapore teacher.
2B and 2C Physics students, can someone summarise the explanation found on the video?
Explanation:Liquid gets pushed into tube by external air pressure.When bulb is released, partial vacuum appears.External air pressure pushes water into this vacuum.Equilibrium:Occurs when both columns are of equal height (forces become balanced, therefore flow is stopped)Column of Water Stays Together:Air pressure (Column pulled apart will create vacuum, air pressure pushes the column back together)
