If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
because the other half is not empty it is filled with gas
A glass column is filled with mercury and inverted in a pool of mercuryThe mercury column stabilizes at a height of 735 mm above the pool of mercuryWhat is the pressure of the atmosphere?
1.034013605
A balloon is filled with CO2 in the same room on the same day at the same atmospheric pressure a second balloon identical to the first is filled with O2 according to avogadro the experimenters?
the same amount of molcules in each A+
Will car tires filled with nitrogen gas ride harder than those filled with air?
With the proper pressure, no.
Which explains the relationship between the gas pressure gradient of the atmosphere and the alveolar air that allows inhalation?
Sub atmospheric pressure in the lungs is generated through sudden expansion caused by the diaphragm and accessory muscles; this sudden and brief pressure gradient is recognized by airflow from the atmosphere into the lungs until they are filled. Once the lungs are filled and achieve a greater than atmospheric pressure another pressure gradient is established and with the assistance of elastic recoil allow exhalation to occur. This end of exhalation provides a temporary period of equilibrium between the lung and outside atmosphere where no air flow occurs. The lungs never totally deflate. The remaining volume left in the lungs after passive exhalation is referred to as the Functional Residual Capacity or FRC. A person can forcefully exhale a portion of their FRC but cannot eliminate all of it; a remaining portion referred to as the residual volume remains. A combination of factors involving surface tension of the alveoli and 0 pressure gradient prevent the elimination of RV.
Which has more buoyant force of atmospheric pressure an elephant or a small helium filled balloon?
Elephant. :)
Why does A balloon filled with hydrogen rises to a certain height then stops rising further?
the atmospheric pressure

How many inches of mercury in a perfect vacuum?
A Standard Atmospheric pressure excerts a force on a mercury filled glass tube with one end closed to make the metal rise 29.92 inches. In a perfect vacuum environment, theoreticaly, there should be no rise on the column of mercury; answer is zero inches.

the same amount of molcules in each A+
Is a fluorescent bulb is filled with gas at a high pressure?
No, just an inert gas and mercury vapor at close to atmospheric pressure. Without the inert gas it would be near vacuum, as very little mercury is needed.
What is the instrument used to determine air pressure is called?
The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with mercury that it turned upside down into another container filled with mercury.
How do you use a manometer?
A manometer is a device that is used to measure the pressure of a fluid. The U-shaped glass tube is partially filled with a liquid, usually mercury. The difference between the height of the mercury corresponds to the difference between the pressure of the fluid in the container and the atmospheric pressure.
Is compressed air more buoyant than atmospheric air?
Since weight is the measure of an object's gravitational pull, the compressed air does not weigh more. The difference is in the density of the air. A tank filled with compressed air will weigh more than a tank that is filled with air at normal atmospheric pressure.
Why is it difficult to operate columns when flooding takes place?
It is simply that you need to be in equilibrum in pressure in the column. Flooding is when you have to much liquid coming down and at it's extreme the column will be filled with liquid. It is the same problem with weaping but in a way the opposite. There is not enough liquid in the column. A column is easier to operate, answers faster and do not overbalance as easily the closer you are to equilibra.
