People breathe in oxygen molecules from the air and exhale carbon dioxide molecules. because of this, the air is full of carbon dioxide and oxygen mixed together. what is this an example of?

a.) an increase in entropy

b.) an increase in oxidation reactions

c.) an increase in enthalpy

d.) an increase in evaporation

! i need the correct answer

~apex~

(A)

This is an example of An increase in entropy

Explanation:

Entropy increases when two gases are getting mixede up. Here carbon dioxide and oxygen are getting mixed together so this will be an example of an increase in entropy.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

idk i’m struggling too
