* Both are made up of matter. This means they both have mass and take up space.
* Both can be physically observed and measured. You can see, touch, and weigh both substances and mixtures.
* Both can exist in different states of matter. You can have solid, liquid, or gaseous substances and mixtures.
However, there are also important differences between substances and mixtures:
* Substances have a fixed composition, meaning the ratio of their components is always the same. Mixtures, on the other hand, can have varying compositions.
* Substances have unique properties that distinguish them from other substances. Mixtures, however, often exhibit properties of their individual components.
* Substances cannot be separated by physical means, while mixtures can be separated using techniques like filtration, evaporation, or distillation.
So, while both are made of matter and observable, their composition, properties, and separability set them apart.
