Document Summary

Tornados: if you measured the temperature outside: Force exerted by air molecules per unit area. Exerted by gravity --> gravitational pull by the earth on the air molecules. Areas on a lower altitude have a higher atmospheric pressure due to a greater amount of overlying air. Near surface, air pressure drops rapidly: with increasing altitude. If an airplane is in flight and there"s a hole in the fuselage, pressure inside the plane will decrease. Most of the air molecules are present close to the ground (at the top of mount everest, you are above 60% of the atmosphere"s molecules) Oxygen deprivation can occur at high altitudes. Questions: if you were suddenly placed at an altitude of 100 km above earth: would you expect your stomach to expand or contract, a standard pressure 1,013. 2 hpa is also known as one atmosphere (1 atm).
