Test Review-SLG, Classification of Matter, and Properties of Matter

2. List the characteristics of a solid.
Definite volume
Definite shape
Crystalline, orderly particle structure
Particles held tightly in place
Least amount of KE

3. When a sample of matter is heated, its particles _____________________.
Move more quickly

4. As the temperature of a gas increases, the volume of the gas will __________________ if the pressure remains the same.
increase

5. List the 3 parts of the kinetic theory.
All matter is composed of particles
The particles are in constant random motion
The particles collide with each other and the walls of their container

6. List the characteristics of a liquid.
Definite volume
No definite shape
More KE than a solid, but less than a gas
Enough KE to escape orderly arrangement
Can flow

7. Why is water unusual?
Water expands as it goes from liquid to a solid (most other substances contract) due to its polarity

8. Compare the speed of the particles in a solid compared to a gas.
Particles move much slower (vibrate in place)

9. List the characteristics of a gas.
No definite volume
No definite shape
Most KE

10. What happens to most matter when it is heated?
The particles gain KE and break attractions to neighboring particles; they take up more space

11. List the characteristics of plasma.
Most similar to a
gas
No definite shape
No definite volume
Composed of
positively and
negatively charged
particles

12. Define heat of fusion.
The amount of energy required to change a mass of a solid to a liquid at the melting point

13. Define heat of vaporization.
The amount of energy required to change a liquid to a gas at the boiling point

14. Define a colloid and give an example.
A mixture with particles large enough to scatter a beam of light; milk or fog

15. What happens when a log burns on a fire?
Mass is conserved; though the ashes have much less mass than the log, matter or mass has not been lost

16. What is another name for a homogeneous mixture?
solution

17. Define a mixture.
a material made up of two or more substances that can be easily separated by physical means

18. What is the Tyndall Effect?
scattering of light by colloidal particles

19. Define a suspension and give an example.
heterogeneous mixture containing a liquid in which visible particles settle; pond water

20. What two categories is matter classified into?
Substances and mixtures

21. What is distillation?
process for separating substances in a mixture by evaporating a liquid and recondensing its vapor

22. What categories can substances be broken down into?
Elements and compounds

25. Classify each of the following as Homogeneous (HO) or Heterogeneous (HE).
Chicken Noodle Soup__HE_______
Chocolate Milk ___HO_______
Cheerios in milk __HE______
Iced Tea with lemon __HO_____
