1 1. What are two properties used to describe matter? Mass AndVolume
2 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 KELiquid – has definite volume and indefiniteshape; low KEGas – has indefinite shape and volume Particles can expand to fill container;high KEPlasma - has indefinite shape and volume ; Highest KE
3 3. Which state of matter has definite volume and definite shape and is most resistant to compression?SOLID
4 4. Which state of matter has definite volume and indefinite shape? LIQUID
5 5. Which state of matter can take the shape of its container and is highly compressible? GAS
7 7. What is not matter (list three things)? LIGHTHEATENERGY
8 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 Decomposition pH Combustibility Toxicity
9 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 substanceExamples :SolubilityViscosityTexturedensity
10 10. Boiling point of a substance can be increased by increasing _____________________. PRESSURE
11 11. Explain the differences between intensive and extensive physical properties. List examples of both.INTENSIVE properties – do Not depend on amount of matterExamples: Density , conductivity, colorEXTENSIVE properties – do depend on amount of matterExamples: mass , volume
12 12. Classify the following as extensive or intensive properties: conductivitysilvermetallicdensitymassmelting pointIntensiveExtensive
13 13. Which state of matter is most resistant to compression? Solid
14 14. What are mixtures?A physical combination of two or more substances, each of which retains its own properties
15 15. List the types of mixtures and give a definition of each. Homogeneous mixture- a physical combination of substances that has uniform composition throughoutExample: salt waterHeterogeneous mixture- a physical combination of substances that does not have a uniform compositionExample: raisin bran
16 16. Salt water is what type of mixture? Homogeneous mixture
17 17. Evaporation, distillation, filtration, and chromatography are all techniques for separating what?A mixture
18 18. What physical property would help you separate a mixture of isopropyl alcohol and water? Boiling point
19 19. Density is what type of physical property (intensive/extensive)?
20 20. Density (does / does not ) depend on amount of substance.
21 21. What is the formula for density? Density = mass / volumeD = mv
22 22. Density will decrease if Mass stays the same and volume increases.
23 23. Which state of matter contains the most amount of kinetic energy? Gas phase(followed by plasma phase)
