1. What are two properties used to describe matter? Mass And Volume
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
4. Which state of matter has definite volume and indefinite shape? LIQUID
5. Which state of matter can take the shape of its container and is highly compressible? GAS
6. List three examples of matter. ROCK AIR STEAM
7. What is not matter (list three things)? LIGHT HEAT ENERGY
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. 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
10. Boiling point of a substance can be increased by increasing _____________________. PRESSURE
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 Extensive
13. Which state of matter is most resistant to compression? Solid
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
16. Salt water is what type of mixture? Homogeneous mixture
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
19. Density is what type of physical property (intensive/extensive)?
20. Density (does / does not ) depend on amount of substance.
21. What is the formula for density? Density = mass / volume D = m v
22. Density will decrease if Mass stays the same and volume increases.
23. Which state of matter contains the most amount of kinetic energy? Gas phase (followed by plasma phase)
Know the hierarchy of matter
Which particle diagram best represents a single element?
2. Which particle diagram represents a single compound? B
3. Which particle diagram represents a mixture of elements?
4. Which particle diagram represents a mixture of compounds?
5. Which best describes the composition of the sample? C. A mixture of compounds
6. Which best describes the composition of the sample? A mixture of elements and compounds
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
A heterogeneous mixture always contains C. Two or more substances that are visibly distinguishable
A thoroughly mixed homogeneous mixture of substances in a single phase is A solution
A mixture that contains particles that settle out is D A suspension
Particles are in a dispersed phase and do not settle out A colloid
