Document Summary
Hydrosphere: liquid river, lakes, oceans, rain, ice water droplets, water vapor. Water (h2o: water has a magnetic polarity, hydrogen bonding, creates surface tension, causes capillarity (soil wet to dry, water as a solution, dissolves many substances. Change in states: evaporation, condensation, freezing, sublimation, deposition. Moves around: moves among the ocean, atmosphere and land. Multiple processes: evaporation, transpiration, evapotranspiration, precipitation, runoff, sinks into soil, recharge of groundwater. Transfer energy: release or absorb latent heat. Humidity: define as amount of water vapor (moisture) in the air, *dry air is actually heavier, maximum humidity of a mass of air increases with rising temperature. Mass of moisture (g) per unit: volume (m3) absolute humidity, mass (kg) specific humidity, saturated mass (kg) relative humidity. Hygrometer: a device used to measure humidity. Absolute humidity (ah: more water vapor, higher ah, given a volume, used by engineers for designing washing machines, max ah increases with rising temperature.
