Is odorless a physical or chemical change?

Answer 1

Yes, most of smells come from esters which can be derived from carboxylic acids, but they also come from adlehydes, ketones, alcohols, and terpenes. These smells get stronger with the greater amount of carbons in a chain or ring. Low molecular weight esters give fruits their odors and flavors while carboxylic acids have a more acrid and repellent stench. All of this is organic chemistry.

Answer 2

Physical because in chemical change two liquids have to mix and the result should be solid.

Chemical changes are color changing, gases coming out, temperature by temperature i mean

whether is it hot or not, and whether its solid or not.
