If Earth's atmosphere were frozen into a solid sphere, what would be its diameter?

Answer 1

If you assume atmosphere is consisted on only nitrogen (solid), the radius of the sphere would be 49.3 km.

Solid nitrogen (at minus 210 degrees Celcius, you can reach) has a density of #10265 ("kg")/"m"^3#. Since the total volume of the atmosphere is #4200000000000000000\ "m"^3#, you can compute mass as #4.31xx10^21\ "kg"#. Since the sphere has a volume of #V=(4*pi*r^3)/3# (r stands for radius), you can compute the radius (and diameter of this sphere) now:

#4200000000000000000*3=4*pi*r^3# or #r^3=1x10^18\ "m"# or #r^3=1xx10^15\ "km"# or #r=1000877\ "m"# or #r=1000.88\ "km"#

Diameter #D=2001.75\ "km"#

The diameter of Earth's atmosphere, if frozen into a solid sphere, would be about 8,760 kilometers.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
