The total pressure of a gas mixture is the sum of the partial pressures of each individual gas in the mixture.
To solve for atmospheric pressure (ATM) in a given context, you typically use the formula relating pressure, volume, and temperature, commonly derived from the ideal gas law: ( PV = nRT ). Here, ( P ) stands for pressure, ( V ) for volume, ( n ) for the number of moles, ( R ) for the ideal gas constant, and ( T ) for temperature in Kelvin. If you're measuring atmospheric pressure, you can also use a barometer or pressure gauge to obtain the value directly. Standard atmospheric pressure at sea level is about 101.3 kPa or 760 mmHg.
An Isobar is a line connection points of equal atmospheric pressure. You would need to have contact with all weather stations to obtain the latest barometric pressure readings. Numerous measurements of air pressure are needed and used
Air pressure in New York, like any location, can vary based on weather conditions and altitude. Typically, it is measured in millibars (hPa) or inches of mercury (inHg). To obtain the most accurate and current air pressure reading for New York, it's best to check a reliable weather website or app.
Plants primarily obtain atmospheric nitrogen through a process called nitrogen fixation, which is facilitated by certain bacteria, such as rhizobia, that live in symbiosis with the roots of leguminous plants. These bacteria convert atmospheric nitrogen (N₂) into ammonia (NH₃), which plants can then absorb and utilize. Additionally, some free-living soil bacteria and cyanobacteria also perform nitrogen fixation. Once converted, nitrogen compounds can be taken up by plants and incorporated into essential biomolecules like amino acids and nucleotides.
No! Pressure is force per unit area: p=f/a. Thus it does not require a large force to produce a large pressure; reducing the area increases the pressure for the same applied force. The thumbtack, for example, can be considered to be a pressure amplifier since a small force applied to the head becomes a very large force at the pointed end of the thumbtack. Not if you have a narrow bore pipe.

Yes, a barometer can be used below sea level to measure atmospheric pressure. However, the reading may be slightly affected by the pressure of the water above it, which needs to be accounted for to obtain an accurate measurement.

Psig (pound-force per square inch gauge) is a unit of pressure relative to atmospheric pressure at sea level. By contrast, psia measures pressure relative to a vacuum (such as that in space). Most pressure gauges, such as tire gauges, are calibrated to read zero at sea level, because most applications require the difference of pressure. At sea level, Earth's atmosphere actually exerts a pressure of 14.695948804 psi. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.695948804 psi. Thus a reading of 30 psig on a tire gauge, represents an absolute pressure of 44.695948804 psi.
No, you cannot use a prescription from another country to obtain medication in your current location.
The instrument used to obtain blood pressure is a sphygmomanometer.
The Barbary pirates operated out of North Africa. They raided European villages; their primary aims was to obtain Christian slaves for the Ottoman slave trade.

Nope.
You might obtain blood pressure by palpation in a noisy environment in which auscultation was not practical. You might also do so with very low or difficult-to-hear pulses.
Bacteria in the soil obtain nitrogen from various sources, such as organic matter, atmospheric nitrogen (N2), and nitrogen-fixing plants. Some bacteria can convert atmospheric nitrogen into a form that plants can use, while others break down organic matter to access nitrogen.
