How does the weight of mercury in a barometer tube compare with the weight of an equal cross section of air from sea level to the top of the atmosphere?

x26quot;The barometer ‘balances’ when the weight of the liquid in the tube exerts the same pressure as the atmosphere outside.x26quot; How does the weight of mercury in a barometer compare with the weight of an equal cross-section of air from sea level to the top of the atmosphere? They are equal

What approximate weight of air is in a column?

is roughly 14.7 lbs per square inch. This means that a column of air 1 square inch in diameter, extending all the way to the top of the atmosphere, weighs 14.7 lbs.

What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature quizlet?

It doubles. What happens to the air pressure inside a balloon when it is squeezed to half its volume at constant temperature? Does the air exert a buoyant force on all objects in air or only on objects such as balloons that are very light for their size? Air exerts a buoyant force on all objects.

When a party balloon is compressed to one third what is the volume?

What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature? The pressure will increase to three times its original pressure.

Why would a water barometer have to be 13.6 times taller than a mercury barometer quizlet?

Why would a water barometer have to be 13.6 times taller than a mercury barometer? Mercury is 13.6 times denser than water. When you drink liquid through a straw, is it more accurate to say the liquid is pushed up the straw rather than sucked up the straw? What exactly does the pushing?

Why doesn’t the size of the tube in a mercury barometer affect the height of the enclosed mercury column?

Why doesn’t the size of a cross sectional area of mercury barometer affect the height of the enclosed mercury column? The height of the column in a mercury barometer is determined by pressure, not force.

Is the pressure within a fluid greater or less in regions where streamlines are crowded?

Is pressure greater or less in regions where streamlines are crowded? Pressure is lower where streamlines are closer.

Would this maximum depth be greater than less than or the same as if he pumps water in San Francisco?

The greater the atmospheric pressure on the surface of water in the well, the deeper the well can be. Since atmospheric pressure is greater in sea-level San Francisco than in higher-altitude Pocatello, maximum well depth for Richard’s pump is greater in San Francisco.

How do you find the mass of a column of air?

So the mass of the column per unit area is equal to the pressure divided by g. I have derived the following for the entire atmosphere massx3dpressurexd7surface areag.

What is the approximate weight of air column over your head?

1000 kg of weight of air is always over your head . Even though air molecules are too small to observe or to see all the molecules of air in the atmosphere above your head weight something . This combined weight of the air resembles a pressure on your body which is approximately equals to 1000 Kg/m.

What is the weight of an air?

The molar mass of dry air is 28.9647 g/mol

What is a column of air?

Air Column means the columns in the Stem and Southeast Leg areas of the terminal that are the source of supply air for these areas. Sample 1.

What change in pressure occurs in a party balloon that is squeezed?

What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature? The pressure will increase to three times its original pressure.

When a gas in a container expands to twice its volume with no change in temperature its density?

QuestionAnswerThe product of gas pressure and volume for a given mass of gas is constantIf the temperature doesn’t changeWhen gas in a container expands to twice its volume, its densityIs half42 more rows

How high would you have to go in the atmosphere for half of the mass of air to be below you?

To find the height at which half the atmosphere is below us, we just need to find the height at which the pressure is half of the sea level pressure, which turns out (from standard atmosphere charts) to be slightly less than 18,000 feet (about 5500 metres).

When a party balloon is compressed to one third its volume gas pressure in the balloon _?

What change in pressure occurs in a party balloon that is squeezed to one-third its volume with no change in temperature? The pressure will increase to three times its original pressure.

What change in pressure occurs in a party balloon that is squeezed to one third?

A balloon when squeezed to one third of its volume, and with no change in temperature the pressure increases up to three times its original pressure. According to Boyle’s law, volume is inversely proportional to pressure.

What happens to the volume of a balloon as it is cooled?

Explanation 1: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. At room-temperature the helium balloon is lighter than air with the same volume of the air, which makes it go up. At low temperatures its volume is too small, so it is heavier than the same volume of air.

When the speed of a fluid increases internal pressure in the fluid quizlet?

101 kPa. Any device that measures atmospheric pressure. An object in the air is buoyed up with a force equal to the weight of displaced air. When the speed of a fluid increases, internal pressure in the fluid decreases

How does the weight of mercury in a barometer compare with the weight of an equal cross section of air from sea level to the top of the atmosphere quizlet?

Why doesn’t the size of a cross sectional area of mercury barometer affect the height of the enclosed mercury column? The height of the column in a mercury barometer is determined by pressure, not force.

What happens to the pressure in the water as it speeds up?

x26quot;The barometer ‘balances’ when the weight of the liquid in the tube exerts the same pressure as the atmosphere outside.x26quot; How does the weight of mercury in a barometer compare with the weight of an equal cross-section of air from sea level to the top of the atmosphere? They are equal

How does pressure change with height in the atmosphere quizlet?

Bernoulli’s Principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases.

What keeps the mercury higher up in the tube of a barometer?

Air pressure pushes down on the surface of the mercury, making some rise up the tube. The greater the air pressure, the higher the mercury rises.

Why is the column of a water barometer much taller than that of a mercury barometer?

A barometer using water, for instance, would need to be 13.6 times taller than a mercury barometer to obtain the same pressure difference. This is because mercury is 13.6 times more dense than water

What are the factors affecting barometer height?

1)The 3 main factors that affect barometric (air) pressure are: Temperature. Altitude or Elevation.Moisture ow water vapour
