GEOG 3 Lecture Notes - Lecture 6: Electromagnetic Spectrum, Sodium Chloride, Volumetric Heat Capacity
Document Summary
Xbt expendable bathythermograph measures temperature as a function of depth- launched from a ship. Heat capacity is important for the entire organism and speci c heat is just for a part. Ocean water is extremely hard to heat and cool. Thermal inertia ywheel effect for heating and cooling water. When tar (oil) gets in sea otter"s or polar bear"s coat they can"t stay warm-try to lick it off (toxic and kills them) Transfer goes down the gradient from the high temperature to the low temperature until equilibrium within the environment of which it"s in is reached. Conduction: metal rod (molecule to molecule up a solid object) Convection: wood for burning res (molecules of air gets heated so their density decreases and become bouyant and go up (molecules move over long distances) Radiation: the sun (electromagnetic spectrum- through radiation itself not molecule to molecule- wavelengths doing heating are invisible) Warm molecules move up in water then move down sides as cool.
