An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam', and σφαῖρα (sphaîra) 'sphere') is a layer of gasses that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
La unidad de presión denominada atmósfera equivale a la presión que ejerce la atmósfera terrestre al nivel del mar. Se ha utilizado para medir presiones elevadas como, por ejemplo, la de los gases comprimidos.
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere.
La atmósfera ( alt. poco común, atmosfera 1 2 ) es la capa de gas de un cuerpo celeste. Los gases son atraídos por la gravedad del cuerpo, y se mantienen en él si la gravedad es suficiente y no es barrida completamente por el viento solar . Atmósfera terrestre. Artículo principal: Atmósfera terrestre.
Standard atmosphere, unit of pressure, equal to the mean atmospheric pressure at sea level. It corresponds to the pressure exerted by a vertical column of mercury (as in a barometer) 760 mm (29.9213 inches) high. One standard atmosphere, which is also referred to as one atmosphere, is equivalent to.
The International Standard Atmosphere (ISA) is a static atmospheric model of how the pressure, temperature, density, and viscosity of the Earth's atmosphere change over a wide range of altitudes or elevations.
