Document Summary
Free convection: vertical mixing - density differences arise from heating of air. Forced convection: turbulent mixing airflow over rough surfaces. The sun is the source of all energy for weather and climate. Radiation- a form of energy due to rapid oscillation of electronic magnetic fields. So solar constant sunspots radiation receipt on a sphere flux density (wm^-2) decreases as zenith angle increase. The flow of heat to a substance will increase the internal energy of that substance. An increase in internal energy will result in a temperature increase, a phase change, or both. There are three kinds of kinetic energy at the molecular level: translational, rotational, and vibrational. Only translational kinetic energy is measured as temperature. For two substances with the same mass and temperature, the one with the higher specific heat will contain more internal energy. Deposition a phase change from gas to solid. Sublimation a phase change from solid to gas.
