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?
The height of the mercury column in the tube represents the balance between the atmospheric pressure pushing down and the pressure exerted by the column of mercury pushing up. With a height of 735 mm, the atmospheric pressure can be calculated as 735 mm Hg or 735 torr.
What is an open arm manometer?
An open arm manometer is a type of device used to measure the pressure of a gas sample. It consists of a U-shaped tube partially filled with a liquid, such as mercury, with one end open to the atmosphere. The height difference of the liquid in the two arms of the tube is used to determine the pressure of the gas.
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 two balloons will have the same number of molecules in them, as they are filled in the same room under the same conditions. Avogadro's law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules.
What column contains elements whose electron configuration end with d4?
The column that contains elements whose electron configuration ends with d4 is the "transition metals" column. Transition metals have partially filled d orbitals in their electron configurations, typically with the d orbitals being filled first before the s and p orbitals.
What kind of apparatus did Boyle use to determine that relationship?
Boyle used a J-shaped glass tube filled with mercury and inverted in a dish of mercury to determine the relationship between pressure and volume of a gas. By varying the amount of mercury in the tube, he could change the pressure applied to the gas. This experiment led to Boyle's Law, which states that the pressure of a gas is inversely proportional to its volume when the temperature is constant.
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
A tank with a flat bottom is filled with water to a height of 4 meters what is the pressure at any point at the bottom of tank can you ignore atmospheric pressure when calculatingyour answer?
The pressure at the bottom of the tank can be calculated using the formula P = ρgh, where ρ is the density of water (1000 kg/m³), g is the acceleration due to gravity (9.81 m/s²), and h is the height of the water column (4 meters). Plugging in these values, we get P = 1000 * 9.81 * 4 = 39240 Pa, or 39.24 kPa.
If a container is half filled with a liquid and sealed at room temperature and atmospheric pressure then what happens inside the container?
Inside the container, the liquid would partially evaporate, creating vapor in the empty space above the liquid. Eventually, an equilibrium will be reached where the rate of evaporation equals the rate of condensation, resulting in a constant vapor-liquid mixture within the container.

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.

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?
To use a manometer, first connect one end to the pressure source and the other end to the point where you want to measure the pressure. Ensure that the manometer is filled with a suitable liquid that will move with changes in pressure, such as mercury or oil. Finally, read the pressure indicated by the level of the liquid in the manometer.
Is compressed air more buoyant than atmospheric air?
No, compressed air is not more buoyant than atmospheric air. Buoyancy is determined by the density of the surrounding medium, so the buoyant force on an object will be the same whether it is in compressed air or atmospheric air.
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.
