Description
Lecture 3: Atmosphere Pressure And Density Atmospheric pressure is the force exerted by air molecules per unit area. • Air is pulled downed by gravitational force; as a result, most of the air molecules are closer to earth. • Highest atmospheric pressure is found closer to earth, because there is a column of air pushing down on the object. Ideal Gas Law states that P= pRT • P is the pressure in Pa (pascals) • p is the air density (kg/m ) • R is the constant in (J/kgK) • T is the temperature in Kelvin (K) Air pressure decreases with the increasing of altitude. • At the top of Mt. Everest, a climber would be above about 60% of the air molecules in the atmosphere. A climber would
