Home Chemistry Substance


Substance, the form of the solid, gaseous, liquid, or plasma form of matter having a definite chemical composition, properties three dimensional structure. The different forms of substances are interchangeable to different states (solid, liquid, gas, plasma). In this part of learning science, we can discuss different topics related to chemical substances and periodic table elements.
