Answer:
The pressure is expected to decrease because as we move up in the atmosphere the is lesser mass of atmosphere weight above us.
Explanation:
The atmospheric pressure is the the force exerted by the layers of the atmosphere above a point. Being a fluid and due to the gravity of earth there is a pressure due to the weight of the atmospheric columns above us.
So, at a height h above the earth surface in the atmosphere the pressure will decrease and this can be calculated as:
[tex]P_h=101325\times (1-2.25577\times 10^{-5}\times h)^{5.25588}[/tex]
putting h=9.6 meter
[tex]P_h=101209.7268\ Pa[/tex]
At an elevation of 9.6 km, the pressure is approximately 254 millibars.
The pressure is inversely proportional to elevation, higher the elevation lower will be the pressure while on the other hand, lower the elevation higher will be the pressure. At an elevation of 10 km pressure drops to 265 millibars then the elevation of 9.6 km, the pressure is approximately 254 millibars.
The atmospheric pressure at sea level is about 1,014 millibars which is equal to the pressure of 14.7 pounds/inch2 so we can conclude that at the elevation of 9.6 km, the pressure is approximately 254 millibars.
