4. As an airplane rises, the surrounding air temperature decreases by approximately 3.25 C for every 500 m in vertical height. a) Complete the table. Height (m) 0 500 Temperature (C) 15.00 1000 1500 2000 2500 3000 b) Is the relationship between height and surrounding air temperature linear or non-linear? Explain how you know. c) This model is considered to be accurate up to a height of 11 000 m. Determine the surrounding air temperature for an airplane flying at this height.
