HOW DOES ATMOSPHERIC PRESSURE HELP US ?

Answer 1

Atmospheric pressure has important effects on water chemistry and weather conditions. It affects the amount of gas that can dissolve in water. More gas, such as oxygen, can dissolve in water under higher pressure when compared to lower air pressure.

Atmospheric pressure doesn’t just help with drinking any liquid with a straw, it’s essential. When you suck on a straw stuck into liquid, it lowers the pressure in the straw. That makes atmospheric pressure higher than the pressure in the straw, which forces the liquid to go up into the straw, and into your mouth.
