#3) Describe the difference between chemical and physical properties and changes of matter? How do these physical and chemical properties relate to intrinsic and extrinsic properties? How are these properties related to the different states of matter? Lastly, how might one classify these different types of matter? Make sure to provide examples of each.
Exercise 1 - Questions 1. Define physical and chemical properties and give at least 3 examples of each type of property. 2. Which substances in Data Table 1 have melting points below room temperature? Are these substances more likely to be ionic or molecular compounds based on melting point alone? Explain. 3.
