Bile will bring about a chemical change to fat. This is because bile chemically alters the way the fat is structured.
physical change
The process of bile is a physical one because it does not contain any enzymes that breaks down any fats. Lipase is the enzyme that breaks down fats but bile is only an emulsifier, which is a physical process, that combines bile with the fats.
Bile is not a chemical, it is bile salts.
Bile is secreted by the liver.
Indirectly in chemical digestion by the release of stored bile into the small intestine. The bile then emulsfies fats.
The liver, pancreas, and small intestine are involved in the chemical and physical changes of fat in the body. The liver produces bile, which helps break down fat globules into smaller droplets. The pancreas releases enzymes that further break down the fats into absorbable molecules in the small intestine.
im not 100% sure but i believe its a chemical change mostly because a chemical change is when the molocules themselves change to create something else and physical is when the molocules only rearange themselves they don't change at all. seeing as how when you digest you do change whatever you have eaten by breaking it down with the acids in your stomach turning it into what comes out next.

Bile. Bile is produced in liver and stored in gall bladder.
Bile itself is not a catalyst; rather, it is a digestive fluid produced by the liver that aids in the emulsification and digestion of fats in the small intestine. While bile salts facilitate the breakdown of fat molecules, they do not change the chemical composition of the substances they interact with, which is a key characteristic of catalysts. Catalysts, by definition, speed up chemical reactions without being consumed in the process, whereas bile is actively involved in digestion.
Enzymes contribute to chemical digestion. They are produced by the pancreas and together with bile, chemically change food into molecules so that it can be absorbed easily by the body.
