If a 10. m3 volume of air (acting as an ideal gas) is at a pressure of 760 mm and a temperature of 27 degrees celsius is taken to a high altitude where the pressure is 400. mm hg and a temperature of -23 degrees celsius, what volume will it occupy? (hint: remember the temperature must be in kelvin)

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
