11) Four phases of matter are:
a) Intermolecular Force (IMF) - force that holds one particle near another particle
Anytime you have a physical change is because the base particle is exerting force on 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 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.
What are the four observation that a chemical reaction occurred. A permanent color change - indicates a chemical reaction Gas is generated. Gas can have an odor or not - it forms bubbles and the bubbles contain the gas that have a “skin”, which is water Energy change Precipitation formed - solid that is forming in a solution
Can any of these observations be also an observation of a physical change/process. Explain.
No because they have different properties. The physical properties of a particle says that the base units do not change, making the observations different.
