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. Which substances in Data Table 1 have melting points above room temperature? Are these substances more likely to be ionic or molecular compounds based on melting point alone?...
Determine whether each statement describes the solid state, liquid state, or gaseous state. Answer Bank gas This state is characterized by the lowest density of the three states. solid liquid liquid This state is characterized by an indefinite shape and high density. solid Temperature changes significantly influence the volume of this state. gas Pressure changes influence the volume of this state more than the other two states. solid In this state, constituent particles are less free to move around than...
2. Consider the phase diagram of compound Z below: Pressure 1.00 lata A 6.5 Temperature a. Label the areas representing solid, liquid, and gas. b. The substance is at point A and the pressure drops to 0.5 atm. What state change will it undergo? (boiling, melting, freezing, etc.)
Melting point can be defined as the temperature when a solid becomes a liquid. The melting point of the chemical acetone is -95
