It will be difficult as the hose is opaque making reading it visually impossible.You will need roughly 30 feet of hose suspended vertically above the bucket with the top end sealed shut and filled with water.
The pressure in the atmosphere and in a liquid both increase with depth. As you go deeper into the atmosphere or the liquid, there are more air or liquid particles above pushing down, which leads to an increase in pressure. This relationship is described by Pascal's principle.
when you drink through a straw you remove some of the air in the straw. because there is less air the pressure of the straw is reduced. but the atmospheric pressure on the surface of the liquid remains the same. henceforth how it helps you drink
I bought a digital weather station recently so I've been studying the various features one of which is a digital barometer. This particular one lets you set the altitude of your house for greater acuracy. A barometer's range as I understand it is from 28 to 32 inches. When the barometer falls it is indicating a change in the weather such as rain or a storm. The lower the number goes the more severe the storm. When it rises it indicates that better weather is coming. Remember, though, a barometer tells you what the weather will be not what the weather is. My instrument seems to predict what the weather will be in about 12 hours with a fair amount of acuracy. By the way the unit I bought was a relatively inexpensive one from Radio Shack and it seems to be fine
I'm just guessing here, but here goes nothing... Presuambly if the ants run quickly for cover, the mercury inside a barometer is going up, showing an atmospheric pressure increase. This may lead to storms
The chamber of a barometer will contract as air pressure goes up. A rise in air pressure pushes the mercury column downward, causing the chamber at the top to become smaller.
air pressure
Air pressure is measured in different ways. Two common ones are PSI (pounds per square inch) or a barometer which measures in column inches of mercury. As we know the barometer goes up and down with weather so the air pressure goes up and down. The highest barometer reading ever recorded is about 32 inches or just over 15.6 PSI. The lowest barometer reading ever recorded was 25.69 in the middle of a hurricane so this is not typical but equates to about 12.5 PSI. These are all sea level readings. So we need an average, or normal. The standard is a barometer of 29.92 which equates to about 14.7 PSI, again being a sea level reading. With that standard the pressure at Denver is 12.1 PSI or a barometer of about 24.63. At this pressure water boils at about 202F instead of 212F.
Barometer's measure air pressure and the Earth's air pressure at a certain place is due to the weight of the air above it. So the higher you go the air pressure drops because there is less air above you pushing down with its weight.
during cold weather like rain storms or snow storms the barometer goes down. During warm weather the barometer goes up.
When the pressure on a gas goes up, the temperature of the gas also goes up. This relationship is described by the ideal gas law. For liquids, the effect of pressure on temperature is less direct and can vary depending on the specific properties of the liquid.

The connection goes like this:The barometer is a device for measuring air pressureAs a storm approaches your location the reading on barometer will dropThe storm may be a lightning stormLightning is static electricity

it goes up. :D
Nothing
More gas dissolves into the liquid.
