capello reaction takes place when it he's into a surface is stronger than the cohesion among the water molecules. and rises through standard cheap inbreeds and stalks all trunks. and copied. in capillaries which are tubes of less than 2 millimeters in diameter water can rise to a certain height. the narrower the capillary the higher the water can rise as a deal amendable unfortunately the chooks the elements of wood through which waters transported have an average diameter of 50 micro meters that 0.05 millimeters that's how narrow the troops are in them water can easily rise to a height of 5 or 10 meters from 14 meter who ishtar but how does it get to the top of a huge 100 meter tall tree for that to occur evaporation comes into play. if i don't see water evaporates in the leaves of the trees crowns that causes suction in the capillaries it's like what happens when we drink from a straw. also clean the function just consider transpiration the loss of water as vapor at the top of the tree cos the pressure differential which sucks water up to such amazing heights calm comes. the if opera
