Today we learned about Water that the part of the Earth is most important. H2O known as Water which consisting 3 atoms. Oxygen creates partial negative charges and hydrogen creates partial positive charge. Surface tension is the inward force, or pull, that tends to minimize the surface area of a liquid. All liquids have have a surface tension, but water’s surface tension is higher than most. Molar mass of water is 18.0 g/mol, but it has a boiling point of 100 degrees Celsius. Hydrogen bonding gives high surface tension, low vapor pressure and high boiling point.
