I have the following question/problem of understanding: I am thinking that the only way force or pressure can transfer in a liquid is by water molecules pushing other water molecules, pushing other water molecules etc. If I put a certain pressure in a closed tank to a certain number of water molecules, and let's say the container get's wider the further away you go from where I apply the pressure, why doesn't the force get divided by the water molecules that are in contact with the ones that I am pushing on? In other words, if I apply a 1 kg/cm2 pressure to however small area of a closed tank, every 1 cm2 of the tank gets the same pressure. How does the force transfer? If I put a pool ball on top of two pool balls, the force gets distributed between the two bottom pool balls, but how does it work in a liquid such that every water molecule gets the same force?
