chemical systems

A chemical system is a specific collection of substances and their interactions, often confined to a particular space or environment. It includes everything inside that boundary—reactants, products, and possibly catalysts—which can change through chemical reactions. Scientists study chemical systems to understand how substances behave and transform under different conditions, such as temperature, pressure, or concentration. These systems help explain natural processes like digestion or photosynthesis and are fundamental in designing new materials, medicines, and energy solutions. Essentially, a chemical system is a way to organize and analyze how different chemicals interact within a defined boundary.
