Dry parcel at sea level is 72F and rises to 2000 ft , what will air temp be at 2000 ft?
2000ft x -5.5ft/1000 ft =-11
72-11=61F
Environmental temperature lapse rate change with heigh from surface to space
Decrease, increase, decrease, increase
Which region of atmosphere has the most heat?
Troposphere
Consider a constant volume of air with constant temperature and pressure. What changes as the air becomes more humid?
Air becomes less dense because the water vapor molecules decrease the mass
