What is the basic instruments for measuring atmospheric pressure?
Atmospheric pressure is measured by a barometer. There are several types. The one most likely to be found in a home is an anaeroid barometer.
What types of equipment would be used to measure the boiling point of a liquid?
You need two tools. To measure the air pressure you use a barometer and to measure the temperature at which the substance boils you use a thermometer. The boiling point is defined as the temperature at which the vapor pressure equals atmospheric pressure.
What are the different types of pressure feet?
water for example.absolute pressure; gauge pressure; atmospheric pressure
How does a barometer work?
There are a couple of types. By far the most common is the aneroid barometer. The heart of an aneroid barometer is a sealed can. As the surrounding pressure rises and falls, the can shrinks and expands. A mechanical linkage translates the deflection into the movement of a dial. It could also be measured with a strain gauge, with the resistance translated into pressure.The Mercury barometer has a tube sealed at the top, full of mercury sitting in a cup full of mercury. A vacuum forms at the top because the exterior pressure can only support a column equal to the height times the density of mercury.Air pressure pushes on the mercury inside of the container, the mercury moves up the glass tube. The greater the air pressure the higher the mercury will rise.
What led to the development of the aneroid barometer?
Evangelise Torricelli invented the mercury barometer in the 1600s. It was very accurate, but it was clumsy to move and had to stay upright. If humans hadn't invented the aneroid barometer, you would see big mercury barometers in all types of transportation.

What is use to measure atmosphere pressure?
Standard atmospheric pressure at sea level is taken as 1 atmosphere for all intensive purposes. Atmospheric pressure near to the surface of the earth is about 1 atm. If we go above it decreases and increases we move towards the center of the earth.
What is the barometer used for and how does it work?
A barometer is an instrument used to measure atmospheric pressure. It can measure the pressure exerted by the atmosphere by using water, air, or mercury. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.
What are three types of isolines?
Isobars - Measure atmospheric pressure Isotherms - Measure temperature Isoheights - Measure elevation

What is the highest air pressure a barometer can measure?
It depends, a barometer can measure many different types of air pressure and there are different kinds of air pressure. your best bet would be to identify what type of barometer you have and simply read a dial. If you don't have a barometer and would just like to know what the maximum registered amount for high pressure is then you should consult you weather records centre. These following records i believe are the most up to date: 1085.6 mb in Mongolia. The lowest recorded air pressure is 850 mbar in Manchester, South Dakota. In theory a barometer can record any amount of air pressure depending on its size. The larger the barometer, the greater range of measurement of air pressure. Currently the worlds largest Barometer resides in the Denmark Visitor Centre. You can find more about this Barometer at: http://www.bertbolle.com/

What is a pressure gauge?
A pressure gauge is an instrument that measures the pressure in a vessel, a line, or whatever the pressure gauge is connected to. Pressure gauges come in at least two different types: differential pressure gauges, and absolute pressure gauges. Differential pressure gauges measure - surprise - DIFFERENCES in pressure. Pressure gauges that read "zero" when not attached to anything would actually be differential gauges that measure the difference between atmospheric pressure and the pressure of whatever they are attached to. Vacuum gauges are differential gauges that measure how far BELOW atmospheric pressure the pressure is in a vessel or pipe. Gauges that measure "gauge pressure" are just differential gauges that are calibrated to measure zero at atmospheric pressure. Absolute pressure gauges would only read "zero" if they were attached to an absolute vacuum. A common type of absolute pressure gauge is a barometer. Strictly speaking, a mercury barometer is really a differential gauge that measures the difference between the vapor pressure of the mercury and the surrounding atmosphere, but the vapor pressure of the mercury is so low that the error in treating it as an absolute pressure gauge is generally negligible. There are many different kinds of gauges used to measure pressure including: Instruments hydrostatic - These measure pressure according the height of a liquid in a column. The height of the liquid is proportional to the pressure. Common types of hydrostatic gauges include: manometers, McLeod gauges, and piston gauges. aneroid - The pressure sensing element may be a Bourdon, a diaphragm, a capsule, or a set of bellows, which will change shape with changes in the pressure of whatever the gauge is attached to. The deflection of the pressure sensing element is read by a linkage connected to a needle or by a secondary transducer. The most common secondary transducers in modern vacuum gauges measure a change in capacitance due to the mechanical deflection. Gauges that rely on a change in capacitance are often referred to as Baratron gauges. Electronic sensors thermal conductivity - including two wire and one wire gauges that measure pressure via changes in the thermal conductivity of the wires as they are placed under strain. Something like this is used in a lot of electronic bathroom scales. ionization gauges - These are primarily used for measurements of low-pressure gasses. They sense pressure indirectly by measuring the electrical ions produced when the gas is bombarded with electrons. Fewer ions will be produced by lower density gases. they have to be calibrated against another type of pressure gauge and depend on the gas being measured.
What are the two types of outside pressures that may act on the outside of an organism?
Atmospheric pressure out side the body and hydrostatic pressure for animals that live in water
Structure of barometer?
nowadays there are many types of barometer. some are automatic and some are manual. so, please name which type of barometer's structure you want to know.
