Properties of Water Ocean motions governed by fundamental physical laws of conservation of mass, momentum and energy Water’s truly unique property as related to Earth System Science: At standard pressure, water changes from a liquid to a solid at 0° C (32°F) and from a liquid to a gas at 100°C (212°F). Only substance that can exist in all three phases within the Earth’s range of temperatures. Other properties of water (additional properties in Table 7.2): - great heat storage ability - little internal friction - dissolves solids and gases readily (“universal solvent”) - changes phase in atmosphere and in ocean - solid form floats - transparent to some wavelengths of light, nearly opaque to others - high surface tension Geography 104 - “Physical Geography of the World’s Oceans”
