What is a simple barometer?
A simple barometer consists of a long glass tube (closed at one end, open at the other) filled with mercury and turned upside down into a container of mercury. The barometer works by balancing the mercury in the glass tube against the outside air pressure, just like a set of scales.
How does a balloon barometer work?
If the pressure of the air outside the jar is higher than inside (high pressure), it will push down on the balloon and the balloon lid will sink and the straw will point up. If the air pressure outside the jar is lower than inside (low pressure), the balloon will swell outwards and the straw will point down.

What is a barometer used for?
A barometer is a scientific instrument used to measure atmospheric pressure, also called barometric pressure. The atmosphere is the layers of air wrapped around the Earth. That air has a weight and presses against everything it touches as gravity pulls it to Earth.

- Cover the top of your container with plastic wrap. …
- Secure the plastic wrap with a rubber band. …
- Lay the straw over the top of the wrapped container so that about two-thirds of the straw is over the opening.
- Secure the straw with a piece of tape.
What is simple barometer explain with diagram?
simple barometer. Explanation: A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. A simple barometer consists of a long glass tube (closed at one end, open at the other) filled with mercury and turned upside down into a container of mercury.
What is a barometer Class 7?
A barometer is an instrument used to measure the air pressure as it varies with distance either above or below sea level. Italian scientist Evangelista Torricelli invented the barometer in the year 1643.

What are the three types of barometers?
This section covers three types of barometer design: cistern, angle or diagonal, and aneroid.
How is a simple barometer constructed for Class 9?
A simple mercury barometer can be made with a clear, dry, thick-walled glass tube about 1 metre ling. The glass tube is sealed at one end and is filled with mercury completely. While filling the tube with mercury care has to be taken so that there are no air bubbles present in the mercury column.
What is a barometer Class 9?
A barometer is an instrument used to measure the air pressure as it varies with distance either above or below sea level.
What is barometer Class 11?
Barometer is used to measure atmospheric pressure at any place above sea level. The barometers are of two types: mercury barometer and aneroid barometer. Now, in both types of barometer the mercury or aneroid is filled in the tube in one hand of the u-tube and the other side is kept open to the atmosphere.
How does a barometer look like?
A mercury barometer has a glass tube that is closed at the top and open at the bottom. At the bottom of the tube is a pool of mercury. The mercury sits in a circular, shallow dish surrounding the tube. The mercury in the tube will adjust itself to match the atmospheric pressure above the dish.
Why are there 2 hands on a barometer?
In an aneroid barometer there are normally two needles. One is the measuring hand and the other is a movable pointer which you can adjust by turning the knob on the front. You should put your pointer needle directly over the measuring hand to set the barometer.
What is barometer explain with diagram?
A barometer is a scientific instrument that is used to measure air pressure in a certain environment. Pressure tendency can forecast short term changes in the weather. Many measurements of air pressure are used within surface weather analysis to help find surface troughs, pressure systems and frontal boundaries.
Why does a barometer have two hands?
In an aneroid barometer there are normally two needles. One is the measuring hand and the other is a movable pointer which you can adjust by turning the knob on the front. You should put your pointer needle directly over the measuring hand to set the barometer.

What does 30 mean on a barometer?
That means a glass tube, with its air pumped out and sealed at its upper end and placed in a dish of mercury at its lower (open) end, would have mercury pushed by air pressure up to a height of 29.92 inches in the tube. An air pressure of 30 inches means the mercury will have risen to a height of exactly 30 inches.

Why do you tap a barometer?
Any dial barometer aneroid or mercury will always have some amount of 'sticktion' therefore a GENTLE tap is normal. (Tapping actually helps the user as it indicates which way the barometer is moving at the time it is being looked at.)
Is 29.89 a high pressure?
Standard temp is 29.92. If you are at Sea Level 29.96-8 is closer to reality and likewise 29.89 etc is normal at higher alts.

What are the 2 hands on a barometer?
The barometer normally has two needles, the measuring hand that displays the current pressure and the movable needle called the setting hand.
Is it OK to tap a barometer?

Where should you position a barometer?
Hang the barometer in a location that works for you. Avoid a location that is exposed to direct sunlight as the temperature changes can affect the readings. Hang the barometer away from drafty locations, like near a door or a window. Air pressure is too variable in these locations.
Is 1024 a high pressure?
A barometric reading over 30.20 inHg is generally considered high, and high pressure is associated with clear skies and calm weather.
