All the following involve an increase in entropy except o most endothermic reactions o sublimation o vaporization o combustion

most endothermic reactions

Explanation:

In endothermic reactions, the entropy of the environment decreases.

The entropy is the measure of the disorder of a specific system.

An endothermic reaction is every chemical reaction in which energy is absorbed.

In a comparison of an endodermic reaction in which energy is released in light or heat form.

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
