Difference (from prior major revision) (no other diffs)

Anytime you have a physical change is because the base particle is exerting force on another particle

Answers these questions as you watch [You Tube Video of Matter - Properties and Change] (If using Edpuzzle, name is Chem328MatterPropertiesChange).

Notes on Properties Webpage

1) What is a property ( use your own words).

2)Which of the two properties changes when the amount of material gets larger. ______

3) Which of the two properties can be used to identify a substance. _____________

4) In a physical properties, what are you not doing to the base units/particles.

5) Define chemical properties (in your own words) -

Notes on Physical and Chemical change

6) Using particle view of matter, what is the main difference between a physical change and a chemical change.

7) Energy changes or flows in every physical and chemical change.

8) Two words to explain where energy is going,
a) Exothermic reaction/process is -
b) Endothermic reaction/process is -

9)What are the two Law of Conservations that must be upheld in any change?

Phases of Matter - Physical Change

10) Since changing phase is a physical change, what can you tell about base unit/particles?

11) Four phases of matter are:
  a) Intermolecular Force (IMF) - force that holds one particle near another particle   b) Solid: def:
     i) Shape:
     ii) Particles spacing:
  iii) Energy: ___ ___ (can overcome IMF or not)
  c) Liquid: def:
     i) Shape:
     ii) Particle spacing:
     iii) Energy _not compressible_(can overcome IMF)
Condensed phase is name people give to either solid or liquid phase

  d) Gas def:
     i) Shape:
     ii) Particle spacing:
     iii) Energy ____(can overcome IMF)

  e) If you significantly more energy to gas particles, then you get
  e)Plasma: def:

Energy is needed to go from one phase to another. Energy is used to change how particles relate to each other and not give energy equally to all particle (called increase temperature).

Notes from Observation of a Chemical Reaction.

12) What are the four observation that a chemical reaction occurred.
a)
b)
c)
d)

13) Can any of these observations be also an observation of a physical change/process. Explain.
