GEOG 2050 Midterm: EXAM #2 - NOTES
Document Summary
Temperature: is the average motion of kinetic energy. Heat: is the transfer of energy from warm objects to cool objects (e. g. gradient or frontal boundary) Sensible heat: is the actual heat we can feel . Developed by daniel gabriel fahrenheit in 1724 (german physicist) Water (h2o) at standard atmospheric pressure (atm) Used in the usa ,belize, jamaica and cayman islands. Developed by anders celsius in 1742 (swedish astronomer) 100 - separates freezing from boiling points. Developed by lord kelvin 1848 (british physicist) 0 k is absolute zero where all molecular motion ceases. 100 k between melt/freeze points and boil/steam points. = (1. 8 ) + 32: fahrenheit to celsius. = ( 32)/1. 8: kelvin to celsius. = 273. 15: celsius to kelvin. Hg becomes solid (freezes) at 39 , 38. 2 . Principal temperature controls: latitude, altitude/elevation, cloud cover, land-water heating differences. In troposphere temperature decreases with altitude: lapse rate. Moderates temperatures: cooler days, warmer nights, most variable part of the climate system.
