To Find: The approximate percent decrease in air pressure.
Answer to Problem 1MPS
Explanation of Solution
Given: As the altitude increase from sea level to 6000 m, the air pressure decrease from 101.3 kilopascals to 47.2 kilopascals.
Original pressure = 101.3 kilopascals
New pressure = 47.2 kilopascals
Change in pressure = 101.3 − 47.2 = 54.1 kilopascals
Change in percentage
Change in percentage
Hence, percentage decrease in air pressure is 53%.
