Atmospheric thermodynamics

Water?s Changes of State Water exists in all 3 states of matter and is made of hydrogen and oxygen atoms. In all 3 stages of matter, these molecules are in constant motion (higher temperature: more movement). Difference between 3 states is the arrangement of the water molecules. A. Ice, Liquid Water, and Water Vapor Ice is made of water molecules held together by mutual molecular attractions.They form a tight, orderly network and don?t move - they vibrate in a fixed position. When ice is heated, the molecules vibrate more, and when the rate of movement increases enough, the bonds between the molecules break, resulting in melting In the liquid state, the molecules are still tightly packed but move fast enough to slide past each other (this causes liquid water to be fluid)

Composition of the Atmosphere Air is a mixture of many discrete gases with their own physical properties in which different quantities of tiny solid/liquid particles are suspended. A. Major Components Composition of air varies depending on the time and place. If H20 Vapor, dust, and other variables were removed from the atmosphere, the makeup is very stable worldwide for an altitude of ~ 80 km. Ni and O2 make up 99% of clean, dry air. They are the most plentiful components, and important to life, but do not affect weather much. The remaining 1% is mostly Argon (0.93%) and other tiny quantities of many other gases. B. Carbon Dioxide (CO2)
