What else can I help you with?
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?
It is a type of manometer, an object used to measure the pressure of different things, and the open armed manometer allows for the atmospheric pressure in the tube of the manometer. So the sample gas pressure pushes on the mercury that is already being pushed on by the atmospheric pressure. Then you add the atmospheric pressure to the change in the mercury (in mm) and that gives you your pressure. It's like a tire gauge.
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 demonstrated this relationship using a U-shaped tube sealed at one end. The tube had mercury added to it so that a volume of gas was trapped at the sealed end of the tube; the gas thus was compressed by atmospheric pressure and the pressure from the column of mercury. Boyle poured mercury into the open end of the U-tube and measured the change in volume of the trapped gas as the applied pressure increased.

How the two types of barometer measure atmospheric pressure?
Barometers measure atmospheric pressure using two main types: mercury and aneroid. A mercury barometer consists of a glass tube filled with mercury, where the height of the mercury column changes in response to atmospheric pressure; higher pressure pushes the mercury up the tube. An aneroid barometer, on the other hand, uses a sealed metal chamber that expands or contracts with pressure changes, moving a needle on a dial to indicate the current atmospheric pressure. Both types effectively provide a measurement of pressure, though they operate on different principles.
Which has more buoyant force of atmospheric pressure an elephant or a small helium filled balloon?
Elephant. :)
What modern meteorological instrument measures atmospheric pressure?
A barometer is the modern meteorological instrument that is used to measure atmospheric pressure. It typically consists of a sealed glass tube filled with mercury that reacts to changes in pressure. The level of mercury in the tube rises and falls depending on the atmospheric pressure.
How is a mercury barometer construct?
A mercury barometer consists of a tall glass tube filled with mercury inverted into a container of mercury. The mercury in the tube will fall until the weight of the mercury column is balanced by the atmospheric pressure pushing down on the surface of the mercury in the container. The measurement is then taken from the height of the mercury column in the tube.
Why human body does not collapse by atmospheric pressure?
The human body is well adapted to withstand the atmospheric pressure. Our internal organs and cavities are filled with fluids that apply equal pressure, counteracting the external pressure. Additionally, our body tissues and structures are strong enough to maintain their shape and integrity under normal atmospheric conditions.
How does the human body resist the atmospheric pressure?
The human body resists atmospheric pressure due to the balance of pressure inside and outside the body. Our body tissues, like skin and bones, provide structural support to prevent collapse. Additionally, air-filled spaces within the body, such as the lungs and sinuses, adjust to equalize pressure changes.
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.
Structure of barometer?
A barometer typically consists of a glass tube filled with mercury or a liquid metal, sealed at one end and open at the other. The open end is placed in a container of mercury, allowing atmospheric pressure to push the mercury up the tube. The height of the mercury column is a measure of the atmospheric pressure.
What is a barometer filled with?
A barometer is typically filled with either mercury or a special type of alcohol, such as ethanol or isopropanol. Mercury has traditionally been a common choice due to its density and stability for measuring atmospheric pressure.
What is a water column test for gas?
A water column test for gas is a method used to measure the pressure of gas in a pipe or system by comparing it to a column of water. In this test, a vertical tube filled with water is connected to the gas source, and the height of the water column is monitored. The difference in height indicates the gas pressure, with higher columns representing greater pressure. This simple and effective technique is often used in HVAC systems, gas appliances, and plumbing applications.
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.
