Heat Index A combination of temperature and humidity which indicates how hot you will feel as a result of humidity's affect on the sweating process.
Absolute Humidity The mass of water vapor contained in a given volume of air. (usu. measured in g/L)
Relative Humidity The ratio of the mass of water vapor in air at a given temperature to the maximum of water vapor the air could hold at that temperature. (expressed as percentage)
Saturated Describes air that contains the maximum amount of moisture that it can hold at a given temperature.
Combustion Burning
Parts per million The number of molecules (or atoms) of a substance in a mixture for every 1 million molecules (or atoms) in that mixture. Abbreviated ppm.
Inert Non-reactive
Greenhouse Affect The process by which certain gases trap heat that radiates from earth.
Global Warming Excess warming of the earth due to too much greenhouse affect.
Carbon Cycle An explanation of where carbon comes from and where it goes in nature.
Industrial Revolution An increase production of carbon dioxide and other greenhouse gases.
When did carbon dioxide concentration begin increasing? Between 1910 and 1925.
When did the temperature begin increasing? Between 1880 and 1895.
Why use ppm? When concentrations are very small ppm is much easier to visualize than percent.
Ozone One of the greenhouse gases that absorb the energy from infrared light, it is also able to filter out the damaging ultraviolet (UV) light from the sun.
Name some possible pollutants. Sulfur Oxides ~ may cause lung damage Nitrogen Oxides ~ may cause lung damage Ozone ~ harmful to lungs if breathed Carbon Monoxide ~ reduces ability of blood to carry oxygen Airborne Lead ~ virtually non-existent today because of safe-guards
Scrubbers Devices in smokestacks of factories which help clean sulfur oxides out of gases produced when fuel burns.
Ultraviolet light A form of light that radiates from the sun which carries enough energy to cause severe damage to living tissue.
