32. To return to the chapter summary click Escape or close this document. Any characteristics of a material that can be observed or measured is a physical property. Physical Properties and Changes The four states of matter are solid, liquid, gas, and plasma. The state of matter is determined by the energy the particles have. 1 1 Reviewing Main Ideas Color, shape, length, mass, volume, density, melting point, boiling point, are common physical properties.

33. To return to the chapter summary click Escape or close this document. In a physical change the properties of a substance change but the identity of the substance always stays the same. Physical Properties and Changes You can classify materials according to their physical properties. 1 1 Reviewing Main Ideas

34. To return to the chapter summary click Escape or close this document. Chemical properties give a substance the ability to undergo a chemical change. Chemical Properties and Changes Common chemical properties include: ability to burn, reacts with oxygen, reacts with heat or light, and breaks down with electricity. 2 2 Reviewing Main Ideas In a chemical change substances combine to form a new material.

35. To return to the chapter summary click Escape or close this document. The mass of the products of a chemical change is always the same as the mass of what you started with. Chemical Properties and Changes A chemical change results in a substance with a new identity, but matter is not created or destroyed. 2 2 Reviewing Main Ideas

36. To return to the chapter summary click Escape or close this document. Question 1 Chapter Review One way to tell whether a change is physical or chemical is to ask yourself: can it be _______? A. contained B. destroyed C. repeated D. reversed PS 3.2

37. To return to the chapter summary click Escape or close this document. Answer The answer is D. Physical changes are usually reversible, whereas chemical changes are generally much harder, or impossible, to reverse. Chapter Review

38. To return to the chapter summary click Escape or close this document. Question 2 Explain the law of the conservation of mass. Chapter Review Answer This law states that the amount of mass you end with after a change will always be the same as the amount you started with. Objects may undergo chemical changes and become different substances, but the amount of mass will still be the same. PS 3.2e
