**Science Review** I. **Definitions** 1. **Physical properties:** Meaning they can be observed or measured without changing the material's composition. 2. **Chemical properties:** Are the characteristics that manifest themselves when there is a change in composition of matter. 3. **Solid state:** have a well-defined shape and volume. 4. **Liquid state:** have a defined volume but they change to the shape of the place they are in. 5. **Gas state:** have no defined shape or volume, so they fill the space of their container. 6. **Pure substances:** contain only one type of particle and their composition is uniform and constant. 7. **Mixture:** is a combination of two or more pure substances. 8. **Heterogeneous Mixture:** are those consisting of pure materials or mixtures of materials that do not combine or have the same proportions. 9. **Homogeneous mixture:** have the same properties, such as texture, color smell or taste throughout.
