Document Summary
Tropopause, zone above troposphere where air temp remains constant with altitude. Stratosphere, increase in air temp, o3 layer (ozone) weatherless zone. Mesosphere, temp decrease, 50-100 km, normal lapse rate. Thermosphere, heat zone inverse lapse rate, high velocity particles. According to wien"s law, the wave length gets smaller and smaller. Max wavelength ( a/t) a is a constant (a=2897) A thing that absorbs all the energy that hits it. Black body is an idealized object that absorbs all electromagnetic radiation that falls on it. 3 laws, describe relation between power and heat. Was coined by james prescott joule in 184 to describe the relations between heat and power. Energy can be transformed but not destroyed, allows work to be done, works in moving things (ocean currents etc) System tends toward equilibrium, that is, a random distribution of energy - entropy. Heat can never pass spontaneously from colder to a hotter body, energy moves down the energy gradient.
