In a liquid, the molecules move past each other but are constantly interacting. What does Enterococcus faecalis look like. Likewise, the high latent heat of vaporization (see below), indicates that when water vapor (derived from evaporation of water at the oceans surface driven by solar energy receipt at low latitudes) condenses into liquid droplets at high elevations or high latitude, the latent heat is released into the environment. As a liquid, water has more directions to move and to absorb the heat applied to it. A high heat capacity means that more energy is required to increase the temperature of water by 1 degree so it requires more time to heat or cool. High specific heat stabilizes ocean temperatures.

Reason for water has a high latent heat: Whats the latent heat of vaporization for water? Water has a high heat of vaporization because hydrogen bonds form readily between the oxygen of one molecule and the hydrogens of other molecules. Although water can evaporate at low temperatures, the rate of evaporation increases as the temperature increases. You can watch vaporization when you boil a pot of water. This process creates two products: water vapor (H2O) and carbon dioxide (CO2). Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (C). Hydrogen bonds keep the molecules far enough apart to make ice about 10% less dense than water at 4C; it is this lower density of ice that allows it to float. Waters high heat of vaporization is important because it helps to moderate the temperature of the ecosystem.
