What measures a barometer with Mercury?
A barometer that uses mercury measures air pressure by monitoring the height of the mercury column in a tube. As air pressure changes, the mercury level rises or lowers in response. This instrument is called a mercury barometer.
When the layer of the air that sorrounds the earth presses down this is called what?
This is called atmospheric pressure. Atmospheric pressure is the pressure exerted by the weight of the air above a given point on Earth's surface.
What is the name giving to a instrument for measuring pressure?
The instrument used for measuring pressure is called a manometer.
What is the relationship of boiling point with atmospheric pressure?
The boiling point of a substance decreases as the atmospheric pressure decreases. This is because lower atmospheric pressure reduces the pressure pushing down on the liquid, making it easier for the liquid to vaporize. Conversely, higher atmospheric pressure increases the boiling point of a substance as more pressure is needed to overcome the atmospheric pressure and cause the liquid to vaporize.
What instrument measures the pressure in an enclosed container of gas?
A manometer is used to measure pressure in an enclosed container of gas. It typically consists of a U-shaped tube filled with liquid that reacts to changes in pressure inside the container. The liquid level in the arm of the manometer connected to the container will rise or fall based on the pressure, providing a measurement of the gas pressure.
What is called the barometer of a circle?
A barometer is an instrument used to measure atmospheric pressure. A circle does not have a barometer!
What instruments are used to measure the atmospheric pressure?
Barometers, such as mercury and aneroid barometers, are commonly used to measure atmospheric pressure. Other instruments like electronic pressure sensors and weather balloons equipped with instruments can also measure atmospheric pressure.
Used to measure atmospheric pressure?
it is called BAROMETER
An airtight instrument composed of thin sheets of metal used to measure air pressure?
The instrument you are referring to is called a barometer. It measures air pressure by using a column of mercury or aneroid capsules to detect changes in atmospheric pressure.
What device or instrument is used to measure air pressure?
If you're asking about a tool to measure the air pressure in a car tire, that is called a pressure guage.If you're asking about a scientific instrument to measure atmospheric air pressure, it is called a barometer.
The measure of the weight of the air above us is called?
Atmospheric pressure.
What is the device use to measure air pressure called?
The device used to measure air pressure is called a barometer. It can be either an aneroid barometer or a mercury barometer, both of which are commonly used to measure atmospheric pressure.
What is the instrument used to determine air pressure is called?
The instrument used to determine air pressure is called a barometer. A simple barometer is a long glass tube filled with mercury that it turned upside down into another container filled with mercury.
How come wind is only measured in a barometer?
Actually, a barometer is an instrument for measuring air pressure, or atmospheric pressure, but not wind speed or the "pressure" of a wind. This atmospheric pressure is caused by the weight of air above the point of measurement. The instrument that measures wind speed is called an anemometer. Wind direction is indicated by a weather vane.
What measures a barometer with Mercury?
A barometer that uses mercury measures air pressure by monitoring the height of the mercury column in a tube. As air pressure changes, the mercury level rises or lowers in response. This instrument is called a mercury barometer.
What is function of a barometer?
To measure atmospheric pressure. In general, higher atmospheric pressures (also called "higher barometric pressure") is generally associated with good weather, while low or falling pressure is generally linked to rain or bad weather.
How does a plane measure alitude?
By measuring the atmospheric Pressure, using an instrument called an Altimeter. As you move higher and higher from sea level, the atmospheric pressure decreases, and the pressure of the air can be converted mathematically to height above sea level . An Altimeter has a dial which shows Metres above sea level. If the instrument is used to measure Atmospheric Pressure , for the purpose of weather forecasting, then the dial shows 'Bars' of pressure. A 'Bar' is equal to 14.7 Pounds per Square Inch of pressure, which is the air pressure at sea level. Sky diving parachutists use an altimeter attached to them , which they can watch as they descend. When their height above the ground is at a suitable height, they open their parachute. They do not just make a wild guess. They use their Altimeter which is quite a good idea. It prevents them from killing themselves !
