In step 4 of Station D, distilled water was added to the test tube. The color of the solution in the test tube after adding the distilled water is different from the color before the distilled water was added. Based on these observations, has a chemical or physical change occurred? Group of answer choices chemical change; the water reacted with the contents of the test tube physical change; the water did not react with the contents of the test tube chemical change; a color change is always due to a chemical change physical change; a color change is always due to a physical change

States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
