The temperature in the sunlight is 120 °C, which is higher than the boiling point of water. The higher up we go, the less air pressure we will encounter. Pressure (symbol: $ P $ ) is the force per unit area applied in a direction perpendicular to the surface of an object. pressure in Pa = (pressure in atm) x (1.01325 x 10 5 Pa/1 atm) pressure in Pa = (99.136 x 1.01325 x 10 5) Pa.  The discrimination is due to the problematic assumptions (assuming a standard lapse rate) associated with reduction of sea level from high elevations. g Cooking at high elevations, therefore, requires adjustments to recipes or pressure cooking. 0 The following is a list of air pressures (as a fraction of one atmosphere) with the corresponding average altitudes. R Enter the value (for example, “15”) into the left, Alternatively, you can enter the value into the right. M − As a whole, the atmosphere of the Earth exerts pressure on the surface of the Earth equal to 100,000 Pascals or 100 kilopascals (kPa). It is common to express atmospheric pressure in terms of the height of the mercury column. 1 New York: Columbia University Press, 1985. New York: Columbia University Press, 1985. Surface pressure is the atmospheric pressure at a point of Earth's surface.  This is in contrast to mean sea-level pressure, which involves the extrapolation of pressure to sea-level for locations above or below sea-level. Air pressure is the pressure of an air column on the Earth's surface. Air Pressure at Altitude Fomula: p = p 0 e-(h/h 0) Where: p: Atmospheric pressure, in Pa p 0: Atmospheric Pressure at Sea Level, in Pa h: Height (Altitude), in meter h 0: Scale Height, in meter Note: The surface pressure on Earth is approximately 1 bar, and the scale height of the atmosphere … 2. This is called 1 atmospheric pressure or 1 atm. Given that the atmospheric pressure at Genting Highland is 72cmHg.
