 Adhesion: ability to stick to solid surfaces Cohesion: ability to stick to itself (surface tension) Water melting point: 0°C, 32°F Water boiling point: hundred degrees Celsius, 212°F Calorie: the amount of heat required to raise the temperature of 1 g of water 1°C Specific heat capacity: the amount of heat required to raise the temperature of unit mass of the substance by 1° Specific heat: the ratio of specific heat capacity to that of water Conductivity: ability to transfer heat Latent heat of fusion: the amount of heat per-unit mass required to change substance at it's melting point completely to a liquid at the same temperature Latent heat of vaporization: the amount of heat per-unit mass required to change a substance at its boiling point completely to a gas at the same temperature Viscosity: inability to flow; Internal friction of the liquid Compressibility: Negligible for most practical purposes, however on global scale it is significant. Without compressibility, oceans would be more than 100 feet higher What is special about the surface tension of water? Higher than normal, exception being liquid metals Capillarity: resulting from a combination of surface tension and adhesion. Ability to climb up a wall Humidity: the amount of water vapor a volume that air can hold at a given temperature and pressure Vaporization: a phase transition from liquid to gas Evaporation: vaporization occurring below boiling point What has an effect on evaporation: Temperature, salinity, water depth, wind, relative humidity Condensation: the change from gas to liquid Dewpoint: the temperature at which saturation occurs and condensation begins Condensation nuclei: tiny particles providing the surface on which water forms Welwitchia: Plant in Namibia that depends almost entirely on dew for water National Weather Service class A pan: 2 feet radius, 10 inches deep Forms of precipitation: drizzle, rain, sleet, snow, and hail Drizzle (size): .1-.5 mm Rain (size): .5-5 mm Convection: heat transfer via motion of fluid Cyclonic precipitation: Occurring at a front, lifting of warm air over cold air Convective precipitation: Attributed to I'm even heating of the ground and adiabatic cooling, occurring mostly in the summer and in the Great Plainsthermal lifting of air to form a thunderstorm cloud Orographic precipitation: associated with windward sides of mountain ranges, often occurring in combination with cyclonic or convective precipitation; lifting against the mountain front Global air circulation order, from poles: Polar cell, polar front, Ferrell cell, horse latitude, Hadley cell, doldrums – ITCZ(Highest salinities at horse--30 degrees, due to evaporation) At 60°: air converges, rises, air pressure is low, climate is wet. Polar Front At 30°: air splits, westerlies towards poles, tradewinds towards equator easterly. Horse latitude Cloud seeding: CO2 pellets are dropped into a cloud; silver iodide is dissolved in a flammable liquid then vaporized in a gas flame to produce smoke Wettest place in the United States: Kauai, Mt. Waialeale Driest place in US: Death Valley, California Driest place in the world: Kalama, desert in North Chili Wettest place for sudden rain: north east India AuthorTipTheScales ID205399 Card SetHydrology Exam 1.txt DescriptionHydrology Exam 1 Updated2013-03-06T17:50:43Z Show Answers
