Water Convection Currents Air Processes Controlling Organisms Heating

Organisms gain or lose heat through exothermic chemical reactions, evaporation, radiation, convection, and conduction.

Os organismos ganham ou perdem calor através de reações químicas exotérmicas, evaporação, radiação, convecção e condução.

Front Processes controlling organisms heating up and cooling down
Back
  • Exothermic chemical reactions
  • Latent heat of evaporation (object cools as water evaporates from surface)
  • Radiation (transmission of EM waves to and from air, water or ground
    • Convection (heating/cooling by currents of air or water, warm air/water rises and cooler sinks, setting up convection currents around organism
    • Conduction (heating due to collision of molecules, ground/water good conductors but air isnt)
