S kinetic energy energy of motion ke = mv2: heat energy and heat transfer. S kinetic energy of atoms and molecules within a substance. N latent heat (stored/hidden heat: evaporation 600 calories per gram of water are added called latent heat of vaporization, condensation heat energy is released. S convection movement of heat energy within a medium (ex: boiling water) S conduction transfer of heat energy between two surfaces in direct contact. N electromagnetic energy energy emitted by the sun. N composition of the atmosphere: major components of clean, dry air. N absorbs heat energy from earth: relative humidity 7,9434190,78,. 9:,,907;,547. 439039 compared with the amount of water vapor required for saturation at that temperature (and pressure) N atmospheric pressure weight of air at sea level: 14. 7 lbs per square inch, 1 kg per square centimeter, milibar (mb) standard sea level pressure is 1013. 2 mb www. notesolution. com.
