Main Difference - Endothermic vs Exothermic Reactions. Osmosis is when a substance crosses a semipermeable membrane in order to balance the concentrations of another substance. Entropy change can be defined as the change in the state of disorder of a thermodynamic system that is associated with the conversion of heat or enthalpy into work. They have both metallic and non-metallic properties. In this branch, the concepts of system and surroundings are used repeatedly. pl.n. Compound Definition: Compounds - Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio. As such, the atom is the basic building block of chemistry. The beaker is the system and the surroundings are everything else, including the lab where the chemist takes measurements. Aimed at graduate students, researchers, academics and practicing engineers and regulators, this book will provide the reader with a single reference from which to learn the fundamentals of classical thermodynamics and radiochemistry. The surroundings are everything outside the system and are the place where the observation and measurements of the system are taken. The negative charge of an electron is equal and opposite to charged proton(s) considered positive by convention. I'm finding these definitions to be crazy ambiguous, and don't thoroughly define what these are. Quantum mechanics has clarified much for physical chemistry by modeling the smallest particles .
