On a acknowledged plane, low-pressure area of cardiac dullness have to a lesser extent atmospherical body above heritor location, whereas high-pressure area of cardiac dullness have to a greater extent atmospherical body above heritor location. Likewise, as elevation

Pressure different swimmingly from the Earth's constructed to the top of the mesosphere
Atmospheric pressure. Although the head changes with the weather, NASA has averaged the conditions for all parts of the earth year-round. As altitude increases, atmospherical head decreases. One can calculate the atmospherical head at a given altitude. Temperature and mugginess also affect the atmospherical pressure, and it is needful to realise these to factor out an precise figure. The exponential curve at right was developed for a temperature of 15 °C and a partner mugginess of 0%.
At low outlook above the sea level, the head decelerate by around 1.2 kPa for all 100 meters. For high outlook inside the troposphere

The high adjusted-to-sea immoderation barometrical head of all time canned on Earth (above 750 meters) was 1,085.7 hectopascals 32.06 inHg calculated in Tosontsengel, Mongolia
Atmospheric pressureon 19 December 2001. The highest adjusted-to-sea immoderation barometrical pressure of all time canned (below 750 meters) was at Agata, Evenhiyskiy, Russia [66°53’N, 93°28’E, elevation: 261 m (856.3 ft)] on 31 December 1968 of 1,083.8 hectopascals (32.00 inHg). The fatism is due to the problematic supposal presumptuous a standard lapse fertility rate associated with reduction of sea immoderation from superior elevations.5

One atmosphere (101 kPa or 14.7 psi) is the head spawn by the weight of a Indian file of newly water ice of approximately 10.3 m (33.8 ft). Thus, a diver 10.3 m underwater occurrence a head of about 2 atmospheres 1 atm of air undetermined 1 atm of water.

Clean newly water ice boils
Atmospheric pressureat around 100 °C 212 °F at earth's standardized atmospherical pressure. The vaporisation attractor is the frigidness at which the vapor pressure
Atmospheric pressureis equal to the atmospheric head around the water. Because of this, the boiling point of water ice is depress at depress head and higher at higher pressure. This is why braising at high elevations call for adjustments to recipes. A potholed version of rise can be obtained by measuring the frigidness at which water ice boils; in the mid-19th century, this method was used by explorers.
An important application of the knowledge that Atmospheric pressure varies directly with altitude was in determining the height of hills and mountains thanks to the availability of reliable pressure measurement devices. While in 1774 Maskelyne was confirming Newton's theory of gravitation at and on Schiehallion in Scotland (using plumb bob deviation to show the effect of "gravity") and accurately measure elevation, William Roy using barometric pressure was able to confirm his height determinations, the agreement being to within one meter 3.28 feet. This was then a useful tool for survey work and map making and long has continued to be useful. It was part of the "application of science" which gave practical people the insight that applied science could easily and relatively cheaply be "useful".
