What does this mean'Fast runs the ants as the mercury rises' Its to do with weather folklore?
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
Can you make a homemade barometer that works?
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.
In What way is the pressure in the atmosphere like the pressure in a liquid?
the deeper it goes, the higher the preassure is
What role does atmospheric pressure play when someone is drinking a liquid through a straw?
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
How does digital barometer work?
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
When the barometer reading goes upwe have a pressure area?
air pressure
Does the chamber of a barometer expand or contract as the air pressure goes up?
EXPAND
What is air pressure at Denver Colorado?
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.

You carry a barometer with you to the top of a very tall buildingyou notice that the barometer reading goes down as you ride up to the107th floorexplain what happened and why?
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.

What happened to a barometer levels when there you cold weather?
during cold weather like rain storms or snow storms the barometer goes down. During warm weather the barometer goes up.
Does liquid Mercury float in water?
No. Mercury is 12.5 times heavier than water. It goes straight to the bottom with no hesitation.
What happens to a barometer when it is about to rain?
it goes up. :D
What happens if a barometer goes up or down?
Nothing
With regard to the effects of pressure on boiling point the change of state from a gas to a liquid is?
the point at which a liquid starts to 2 boil is defined by when the pressure inside the liquid is equal to the atmospheric pressure. so the higher the altitude the lower the pressure, which means the temperature at which the liquid will start 2 boil will b lower. this applies for when a gas goes to a liquid as well
