Gas in a cylinder initially at a temperature of 290K and a pressure of 1.013xd 10 pa is compressed to one-cight of its initial volume.
The pressure differences for isothermal compression is
A. 8.013:10 pa
B. 1.013 x10 pa
C. 6.013 x 10 pa
D. 7.091310 pa
E. 2.031 310 pa
21. The pressure differences for adiabatic compression is
A.24 kpa
B.16.7 kpa C. 6.031x10pa
D. 36 pa E. 17.605x10 pa

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.
