Question

Air pressure at 5500 m (18,000 ft.) is __________ percent of that at sea level.

A) 50%
B) 25%
C) 10%
D) 5%

Answer 1

The air pressure at 5500 m (18,000 ft) is approximately 50% of the air pressure at sea level.

Step-by-step explanation:

The air pressure at 5500 m (18,000 ft) is around 50% of the air pressure at sea level. This means that the air is less dense at higher altitudes due to a decrease in the weight of the air column above. This decrease in air pressure can affect various physical phenomena, such as boiling points and partial pressure calculations.
