Document Summary

Concept of wavelength-suns energy comes as electromagnetic waves. Sept. 13th 2017 from the sun and long comes from the earth. Concept of electromagnetic spectrum: endogenetic energy (<1%) The global energy system: global energy system as a black box, energy transfers and transformations (1, heat energy. Conduction transferring energy- the difference in temperature dn an objects ability to absorop and transport heat. Humans are transferring heat all the time because our internal temperatures are higher then the air and objects around us. Radiation is also transformed into chemical and kinetic energy for photosynthesis: laws of thermodynamics. Because the refrigerator expels heat while it is running. How much energy is emitted by a black body (a perfect emitter)-any object will emit as long as it is a black body. Water is pretty close to a black body. Where: e is the intensity of radiation emitted by a black body. : is the stefan-boltzmann constant (5. 6 x 10-8 w m-2 k-4)
