Click hereto get an answer to your question ️ What is the increase in entropy when 11.2 L of O2 are mixed with 11.2 L of H2 at STP ? Thus when a system goes from a more orderly to less orderly state, there is an increase in its randomness and hence entropy of the system increases. Contributors; A very useful, though somewhat rough, description of the entropy of a substance is as a measure of the randomness or disorder of the atoms and molecules which constitute that substance. Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system.
