Model the data into a mathematical function with pressure in Pa as a function of altitude in meters. 3. According to the data what is the base value of atmospheric pressure? s this number the same as the know value or 1 ATM? If not, can you think of a reason for why it is different? 4. It is known that the air pressure varies exponentially with altitude. P- P.Where h is the altitude in meters and H is the scale height. Puurface 101325 Pa. The scale height, H, is the height above the surface at which the pressure would have reduced to a value of 0.368 of its value at sea level. The pressure at 5000 m is given to be 51271 Pa. According to the formula, what is the scale height, H? How does this height compare with the value from the data table above? Explain the difference, if any Part III Class Activity.
