Document Summary
H20- hydrogen is more positive, oxygen is more negative. Cohesion mutual attraction> water drops are round. Adhesion- attraction to other molecules >water is wet. Latent head of vaporization requires 540 calories (to cause vapor) Latent heat of melting 80 calories( to get to 100) Latent heat vs high heat capacity water has a lot of high heat capacity, latent heat is the heat that you have to put in to change states. Fresh water stratification surface cooling- sturs water up. 98% of the energy at the top of the atmosphere. Only a thin layer of water is illuminated by the sun ( blue is the strongest) Waves are refracted toward regions of lower speed . Speed of sound decreases with temperature and increases with pressure. So the path of wave curves and the waves are refracted toward the lower velocity. Water is a polar molecule accounting for waters unusual properties.
