Atmospheric pressure

How and by how much hPa will the atmospheric pressure change when we take the cable car from Skalnate Pleso to Lomnický štít?
The altitudes of the cable car stations are 1754 m above sea level and 2634 m above sea level.

Correct answer:

Δ =  -80.32 hPa

Step-by-step explanation:

p0=1013.25 100=101325 Pa g=9.81 m/s2 ρ=1.2 kg/m3 h1=1754 m h2=2634 m  p1=p0 ep0ρ g h1=101325 e1013251.2 9.81 175482644.8398 Pa p2=p0 ep0ρ g h2=101325 e1013251.2 9.81 263474612.9029 Pa  Δp=p2p1=74612.902982644.83988031.9369 Pa Δ=Δp/100=(8031.9369)/100=80.32 hPa
