Evaporation, condensation, and precipitation are all parts of the water cycle. So the answer would have to be the water cycle.
C. Temperature of the chamber. As temperature increases, pressure increases. As temp decreases, pressure decreases.
B. because the other options are different sciences (biology and entomology)
Explanation:
The given data is as follows.
Concentration = 3.3 mol
Rate constant = 
Molecular weight = 55000 g/mol

Initial concentration (
) of aminoheptanoic is 3.3 kg/mol.

Hence, putting the given values into the above formula as follows.

= ![\frac{3.3}{2.74 \times 10^{3} kg/mol min} [X_{A}]^{0.1}_{0}](https://tex.z-dn.net/?f=%5Cfrac%7B3.3%7D%7B2.74%20%5Ctimes%2010%5E%7B3%7D%20kg%2Fmol%20min%7D%20%5BX_%7BA%7D%5D%5E%7B0.1%7D_%7B0%7D)
= 120.43 min
Thus, we can conclude that total time required to to form polyamide is 120.43 min.
