Which statement accurately describes a difference between a mercury barometer and an aneroid barometer?
A mercury barometer uses a column of mercury to measure atmospheric pressure, while an aneroid barometer uses a flexible metal box to measure pressure changes. Mercury barometers are more accurate but require careful handling due to the toxic nature of mercury, while aneroid barometers are portable and safer to use.
What is the difference between an anemometer and a wind vane?
Anemometers measure wind speed, wind vanes tell the direction from which the wind is coming.A wind vane measures the direction of the wind.An anemometer measures the speed of the wind.A wind vane tells you which direction the wind is blowing, the anemometer tells you the speed.
Is an anemometer is a glass tube sealed at one end and placed in a container of mercury?
No, an anemometer is a device used to measure wind speed and direction. It typically consists of cups that rotate with the wind or a propeller that spins in the wind. The description you provided sounds more like a barometer, which measures atmospheric pressure using a column of mercury in a sealed glass tube.
What is the name of barometer which does not contain liquid?
It's known as an aneroid barometer. It works by the difference in pressure causing a partially flattened tube which is wound into a coil to straighten out. The movement is converted to circular motion by a series of gears. the central shaft has a needle attached which indicates the pressure.
What is the different between barometer and thermometer?
A barometer measures the barometric pressure of the atmosphere. This has to do with the relative humidity. The more moisture suspended in the air, the more it weighs. A weather thermometer measures the temperature of the air.
Is wind speed measured by a barometer?
No. A barometer measures pressure. Wind speed is measured by an anemometer.
What is the device used to mesure pressure and wind?
A barometer is a device used to measure atmospheric pressure, while an anemometer is used to measure wind speed and direction.
What is the difference between Mercury barometer and a aneroid barometer?
their spelling is different.
Which instrument is used to detect how air is moving?
Weather Vane Wind socks Anemometer Beaufort Scale
What are five weather instruments?
barometer, anemometer, thermometer, hygrometer, and a wind vane.
Is an anemometer used to measure air pressure?
No, an anemometer is used to measure wind speed and direction, while a barometer is typically used to measure air pressure.
What is the difference between anemometer and hygrometer?
An anemometer measures wind speed. A hygrometer measures relative humidity. Two different things entirely.
When did Torricelli invent the anemometer?
Evangelista Torricelli did not invent the anemometer; however, the first known description of an anemometer was by Leon Battista Alberti in the 15th century. Torricelli did invent the mercury barometer in the 17th century, which measures atmospheric pressure.
What does barometer anemometer thermometer hygometer weather van mean?
What does thermometer ab baromean mean.
Name four science weather tools?
thermometer, barometer, anemometer, Doppler radar.
An instrument used to measure wind speed is a(n)?
compass points. Usually a wind vane which swings into line with the direction of the wind.
What instruments tell you in which direction the wind is blowing an anemometer barometer a wind vane a therometer?
a wind vane
