𝐄𝐧𝐭𝐫𝐨𝐩𝐲: Entropy is a measure of disorder or randomness in a system. It quantifies the amount of thermal energy unavailable to do work. According to the second law of thermodynamics, entropy tends to increase over time, meaning systems naturally evolve toward greater disorder and less organization. This concept applies broadly, from physical systems to information theory and beyond. | Chemistry Help
