Question

atmospheric pressure decreases by about 12% for every 1000 meters you climb. The pressure at sea level is about 1.013 atmospheres. Construct a model to represent the atmospheric pressure at a given altitude in thousands of meters

Answer 1

That would, of course, be
P(h) = 1.013 * 0.88^x
where x is in thousands of meters

Answer 2

For every 1000 m of ascent,the temperature decreases by 6 degree celsius
