2. What are the states of matter and their differences in terms of kinetic energy?
• Solid – has definite shape and definite volume particles vibrate in place; very low KE
• Liquid – has definite volume and indefinite shape; low KE• Gas – has indefinite shape and volume
Particles can expand to fill container;high KE• Plasma - has indefinite shape and volume ;
Highest KE
3. Which state of matter has definite volume and definite shape and is most resistant to compression?
•SOLID
8. Define and give examples of the chemical properties of matter.
Chemical properties – the ability of a substance to undergo a
change that transforms it into another substance
Examples - Reactivity DecompositionpH CombustibilityToxicity
9. Define and give examples of the physical properties of matter.
• Physical property –• A characteristic that can be observed without
changing the identity of the substance• Examples :
• Solubility• Viscosity• Texture• density
11. Explain the differences between intensive and extensive physical properties. List examples of both.
• INTENSIVE properties – do Not depend on amount of matter
• Examples: Density , conductivity, color• EXTENSIVE properties – do depend on amount
of matter• Examples: mass , volume
12. Classify the following as extensive or intensive properties:
• conductivity• silver• metallic • density • mass • melting point
• Intensive• Intensive• Intensive• Intensive• Extensive• Intensive
14. What are mixtures?
•A physical combination of two or more substances, each of which retains its own properties
15. List the types of mixtures and give a definition of each.
• Homogeneous mixture- a physical combination of substances that has uniform composition throughout
• Example: salt water• Heterogeneous mixture- a physical
combination of substances that does not have a uniform composition
• Example: raisin bran
17. Evaporation, distillation, filtration, and chromatography are all techniques for separating
what?
•A mixture
18. What physical property would help you separate a mixture of isopropyl alcohol and water?
Boiling point
23. Which state of matter contains the most amount of kinetic energy?
•Gas phase• (followed by plasma phase)
25. Distinguish between 4 states of matter.
• Drawing 1 =• solid• Drawing 2 =• gas• Drawing 3 =• plasma• Drawing 4 =• liquid
Distinguish between solution, colloid, and suspension.
• Drawing 1 = • solution• Drawing 2 =• suspension• Drawing 3 = • colloid
