Document Summary
Electrostatic attraction between partial + and 0 charges on separate polar molecules h-bonds (weak bonds holding water molecules together) - unchanging strength. Thermal/kinetic energy (pushes/breaks adjacent molecules apart) - increases with increasing temp. Amount of energy needed to change phase and temperature of water. Heat required to convert 1 gram of solid ice to liquid water. Heat required to raise 1 gram of water by 1 degree celsius. Water has one of the highest of any substance on earth. Amount of heat required to convert 1 gram of liquid water to vapor water. An important consequence of water"s exceptionally high specific heat capacity: Takes a lot of heat to increase temp of water. You owe a big thank you to the ocean for greatly attenuating the magnitude of global warming. Evaporation moves latent heat from the ocean to the atmosphere. Condensation: latent heat released into atmosphere by condensation of water vapor to form clouds and rain.
