What does rising atmospheric pressure usually indicates?
a high pressure system is moving into an area
Which weather condition is usually found when it rains?
Low atmospheric pressure at the rainy location.
Where can i buy liquid mercury from?
Firstly a barometer does not use mercury to measure atmospheric pressure.Secondly you need to have a license to handle mercury since it is a very dangerous material.Some barometers do use mercury, but not to directly measure the atmospheric pressure. It was used because air did not mix with the mercury because of the density.So the air would "push down" on the mercury, pushing it up another tube that had a measuring system on it, usually metric.This is where we get the pressure unit Torr, which is 760mmHg, which is 1 ATM (atmosphere), the pressure at sea level.
How can pressure help us predict weather?
Low pressure usually bring lousy weather. A barometer measures atmospheric pressure. High pressure is associated with good weather low pressure with bad weather
What causes Back pressure on cooling system?
Condenser Backpressure is the difference between the Atmospheric Pressure and the Vacuum Reading of the Condenser, that is: Backpressure = Atm. Pressure - Condenser Vacuum Pressure Reading Usually, the condenser vacuum pressure is read by a manometer installed at the condenser. The atmospheric pressure is read using a barometer
Does rain usually occur in high atmospheric pressure or low atmospheric pressure?
rain occurs in low atmospheric pressure.
What can a barometers be used for?
A barometer measures barometric pressure, that is, atmospheric pressure. Because air flows from high pressure areas to low pressure areas, rising or falling barometric pressure tells us that we should expect a change in the weather. For example, a storm is often preceded by a drop in barometric pressure. A barometer is an indispensable tool for a meteorologist, a captain of a ship, or anyone else who needs to predict the weather.
Does high atmospheric pressure usually accompanies a tornado?
No, tornadoes are accompanied by low pressure.
What does rising atmospheric pressure usually indicates?
a high pressure system is moving into an area
What is the atmospheric pressure on a pie chart?
The same as the atmospheric pressure on anything else on the surface of the earth.
Would you consider atmospheric pressure when finding the pressure of a liquid in a closed container?
pressure is usually measured relative to atmospheric this is called gauge pressure. if you compare against absolute zero pressure (vacuum) this is called absolute pressure.
What does it mean when the atmospheric pressure at place fall suddenly?
A drop in pressure usually indicates bad weather.
What does it mean when the atmospheric pressure at a place fall suddenly?
A drop in pressure usually indicates bad weather.
What instruments are used to measure the atmospheric pressure?
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.
Which weather condition is usually found when it rains?
Low atmospheric pressure at the rainy location.
Which atmospheric variable usually increases before precipitation occurs?
barometric
What are the controls in a lab?
Temperature: usually room temperature (25 degrees Celsius) Atmospheric pressure: usually 1atm
