Water is the only known substance on Earth that exists naturally in three states: solid, liquid, and gas. Water, for example, is made up of two hydrogen atoms and one oxygen atom. In a physical change, a substance’s physical properties may change, but its chemical makeup does not. This concept is called the Law of Conservation of Mass. The same amount of matter exists before and after the change-none is created or destroyed. Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. It includes molecules, atoms, fundamental particles, and any substance that these particles make up. Matter is anything that has mass and takes up space. Atoms that were in a dinosaur millions of years ago-and in a star billions of years before that-may be inside you today. And because matter is never created or destroyed, it cycles through our world. The most reliable way of making sure whether there has been a chemical reaction vs physical change is by doing a chemical analysis like mass spectroscopy of the starting materials and the end product.Matter makes up everything visible in the known universe, from porta-potties to supernovas. Sometimes chemical changes occur even if they only show the signs of a physical change. However, physical change can also cause a dramatic change in a substance’s appearance. How To Differentiate Between Chemical Reaction Vs Physical Change?Ī chemical change may not show all the signs we have mentioned above and if you do not see any of the above-mentioned signs of a chemical change, then there has likely been a physical change. Moreover, a precipitate is formed, temperature changes, and light is also produced. ![]() There is sound production as well as a change of color. Whenever a chemical change occurs there is some sort of gas production and sometimes bubbles are also produced along with odor. In a chemical change, the atoms of the substance get rearranged and the end result has completely new molecules that cannot be transformed back to their original state. When a substance undergoes a chemical change, its composition gets changed as well, which requires the breakage and production of new chemical bonds through a chemical reaction. This one is quite interesting because even though there is a color change, the chemical structure remains the same. ![]() Solid sulfur melted into liquid sulfur is also an example of physical change.Filling a bowl with different types of candies and chocolates. ![]() A mixture of oil and water is also an example of two different ingredients going through a physical change.The changing of carbon from graphite to diamond. ![]()
