Your elevation above sea level or the weather passing over you.
Increased altitude means decreased air pressure.
there must be vacuum in the mercury barometer because if air enters the tube the barmeter would become faulty as air pressure will change.
if the dna sequence of a gene was tacttaccgagctagact then what kind of mutation has occured This has nothing to do with the question of air pressure. Either a change of temperature or a change of volume can affect air pressure, according to Boyle's Law of Gases. Increasing temperature=increased air pressure Decreased volume=increased air pressure The reverse is also true. Decreased temperature=decreased air pressure Increased volume=decreased air pressure
Air pressure decreases.But when air gets colder it increases.
the air pressure increases
the air pressure increases
No. You can see it expand the object that is containing the air as the air pressure increases.
The higher up you are the lesser the air pressure in the atmosphere.
"Constant pressure" means the pressure must not change.
Sudden change in air pressure might lead to death. Sudden change in air pressure will disrupt the blood and air circulation within your body. You might feel dizzy and have nose-bleeding in such cases.
As the amount of air above us decreases...the air pressure decreases.
Increased altitude means decreased air pressure.
