Question

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 enthalpy b. an increase in entropy c. an increase in evaporation d. an increase in oxidation reactions

Explanation:

Entropy is a measure of disorder. Mixing different gas molecules (oxygen and carbon - dioxide in air) increases the disorder of the system. Enthalpy is related to heat content, evaporation is about a liquid - to - gas phase change, and oxidation reactions involve electron transfer. Here, the mixing of gases is an example of increased entropy.

Answer:

B. An increase in entropy
