What is the temperature around an aeroplane flying at an altitude of 4000 metres if the temperature on the earth surface is 40 oC?
Answer Details
Initial temperature = 40oC Final temperature = ? According to lapse rate 1000m ascent = 6.5oC decrease in temp. 4000m =x 4000 = 6.5 x 4=26.0oC Final temp. = (40o -26o)C=14oC
