Document Summary
Properties of the atmosphere: temperature, pressure, moisture, wind. *relationships between these properties make things more complicated: temperature. Kelvin scale: devised by william thomson (1824-1907) who later received the title. Based upon the concept that 0 degrees is set to an energy state in which there is no molecule movement. Absolute zero (0k) = -459. 67 deg f = -273. 15 deg c. Absolute values different, but increment the same 1 deg increase in c = 1 deg increase in k. No negatives in kelvin lowest temperature is 0 deg k. Temperature is a measure of average speed of molecule movement in a substance. The more energy the molecules of air, water, etc. have, the higher temperature. This movement is faster for higher temperature and slower for lower temperatures. Absolute zero = energy in the molecules is zero. Background temperature in space is 3 or 4 k, close to absolute zero (0 kelvin)
