What would happen to a mercury barometer when the air pressure is getting lower?
The height of the column of mercury would be lower.
What role does pressure play in getting water from its source to your sink?
In order for water to reach your sink, pressure needs to be exerted for it to beat gravity's force.
How could you use an inflated balloon to show that decreasing the volume of a fixed mass of air increases its pressure?
You could do this by applying pressure to the balloon, you'll notice that as it get's smaller from getting squeezed it becomes harder to compress, because of the higher pressure.
Why would your air conditioner have a normal suction pressure and low head pressure with a 14 degree temperature difference?
What type of low head pressure are we talking about? List the pressures and refrigerant type along with the indoor and outdoor conditions at the time the pressures were observed and we can be of more help. I've done a few new installs lately. residential splits, r22 and normal conditions say 80 degrees and not humid. when charging the units i was getting a good suction pressure, around 68-70psi, the suction line was coming back nice a cold and the liquid line was warm. but for some reason i was getting a super low head pressure, around 150-175psi. any ideas cause im at a loss. i did everything right and the systems were even running great. any help would be appreciated. if the indoor space was warm that wouldn't drop my head pressure right, i thought it would be high
What is the water pressure at 66 feet under water?
The perfect answer requires understanding of the density of the water at different temperatures and pressures at all levels of depth. NOTE: The distinction between PSIG and PSIA is that PSIG is pressure as compared to local (atmospheric) pressure which becomes negative for a vaccum (pressure less than the local pressure). O PSIA is a perfect vacuum and normal atmospheric pressure is ~14.7 PSIA (0 PSIG when referenced to atmospheric local pressure) Without getting too "deep" into the perfect answer, using an approximation thumbrule of 1/2 psi increase per 1 foot of water depth, the answer is approximately 328 PSIG or ~ 343 PSIA.
How can you use a barometer to detect changes in air pressure?
A barometer is used in 2 ways. First you keep it stationary. You record the pressure. If the pressure drops, it means, a storm is coming. Second, in a car or airplane when the barometer falls, it means you are getting higher. When the barometer drops, it means you are getting lower.

What type of weather will generally a rising barometer reading?
A barometer measures air-pressure (baro-meter) so a rising reading means the local air pressure is increasing. If we assume that your local gravity is constant (it usually is) then the increasing air pressure is caused by the air getting denser; more kilograms per cubic metre or pounds per pint. That could be because the air is getting colder, or because it has less water content, since making air colder makes it denser, and dry air is denser than wet air. So, a rising barometer suggests a spell of cool dry weather.A rising barometer indicates that the air pressure is rising and this is associated with clear skies with few cloud formations. Generally this will mean it is hotter than average in summer, but colder than average in winter.A rising barometer means higher pressure which means less clouds and fairer weather.

How do scientists predict weather by using a barometer?
Very simply put, cold air is denser than warm air - thus as air of differing temperature passes over you (or rather your barometer) the barometric pressure will change. The arrival of warm air will cause the barometric pressure to fall and as warm air holds more moisture than cold air a falling barometric pressure will herald the arrival of rain. Conversely, if the pressure rises this will indicate some nice sunny days to come Further, if the pressure falls (or rises) fast, then there are likely to be strong winds.
1998 Chevy silverado will not startI am getting sparkfuel pressure is ok.Any help will be greatly appreciated?
If it is injected you might not be getting enough fuel pressure. Check fuel pressure regulater
