chemical change and which represents a physical change? Explain your answer. Describe the difference between a heterogeneous mixture and a homogeneous mixture, and give an example of each Construct a concept map that includes the following terms: atom, element, compound, pure substance, mixture, homogeneous, and heterogeneous. MATTER AND CHANGE gas is a change in state. Other kinds of physical changes are dissolving, bending, crushing, and ﬁltering. The other way that matter can change is a chemical change. In a chemical change, matter changes into one or more new substances. Unlike a physical change, a chemical change produces new substances with different properties from those of ... Heterogeneous Mixtures A mixture that doesn't have a uniform composition. Uneven distribution of components. Extensive Properties Physical properties that depend on the quantity of the material. Homogeneous Mixtures Chemical Properties Physical Properties Property hat describes
Classification of Matter Properties of matter All matter can be classified as either a mixture or a pure substance Matter has two properties, physical and chemical Chemical property Pure substances Mixture Physical property Chemical properties are properties that are only evident.

Qualitative Definition of Energy Most dictionaries define energy as “the capacity to do work.” This implies that energy is a more abstract concept than work. The definition is correct, of course, but it is ...
