Write a short note on atmospheric pressure and it's effects and uses .
Answers
Answer:
Explanation:
Atmospheric pressure is an indicator of the weather. When a low-pressure system moves into an area, it usually leads to cloudiness, wind, and precipitation. High-pressure systems usually lead to fair, calm weather. A barometer measures atmospheric pressure, which is also called barometric pressure.
Effects
Effects of changes in air pressure and density on the human body. Humans can survive up to about 20,000 ft (3.8 miles) above sea level. Above about 20,000 ft, the human body begins to suffer a condition called hypoxia in which the brain does not receive sufficient oxygen for long-term survival.
Uses
The pressure of the atmosphere is responsible for making almost everything involving the pseudo force of suction work. Straws, suction cups and vacuum cleaners are only possible due to the forces exerted by atmospheric pressure. Suction isn’t really a thing. Instead, atmospheric pressure exerts forces towards regions that have had their pressure lowered by some means.
