The air pressure. the air pressure increases as the altitude an object is at increases.
no because they are two diffrent things
Answer:
8.354 nanometers
Explanation:
To treat a diffusive process in function of time and distance we need to solve 2nd Ficks Law. This a partial differential equation, with certain condition the solution looks like this:

Where Cs is the concentration in the surface of the solid
Cx is the concentration at certain deep X
Co is the initial concentration of solute in the solid
and erf is the error function
Then we solve right side,

And we need to look up the inverse error function of 0.001964 resulting in: 0.00174055
Then we solve for x:

Empirical formula is the simplest way the molecular formula can be wrote so here 7 goes into all of these so it would be CH2O
Thick liquid lava
It's right
