Kinetic Particle Theory
States of matter
Liquid
- No fixed shape
- Fixed volume
- Cannot be compressed
- Particles are less closely packed in a disorderly manner
- Strong FOA
- Slides over one another
-
Gas
- No fixed shape
- No fixed volume
- Can be compressed
- Particles are far apart and randomly arranged
- Weak FOA
- Move randomly at high speeds
-
-
Solid
- Fixed shape
- Fixed volume
- Cannot be compressed
- Particles are closely packed
- Strong FOA
- Vibrate about in fixed positions
-
-
Diffusion
The net movement of particles through a partially permeable membrane from a region of higher concentration to a regions of lower concentration until equilibrium is reached
-
Element
- Pure substance in it's simplest form
- Cannot be broken down into simpler substances
- Homogenous
- Fixed composition
- Fixed MP and BP
-
-
-
Acid
-
-
Properties
- Sour taste
- Dissolve in water to form solutions which conduct electricity
-Turns blue litmus paper red
- Acid + ACTIVE metal = salt + hydrogen (displacement reaction)
- Acid + Base = Salt + water (neutralization)
- Acid + Carbonate = salt + water + carbon dioxide
Mixtures
- Two or more substances that are physically combined
- Non homogenous
- Varied composition
- Not fixed MP and BP
- No energy change when formed
- Properties same as the substances that make up the mixture
-
Alkali
-
Properties
- Bitter taste and feel soapy
- Turn red litmus paper blue
- Acid + Base -> salt + water (neutralization reaction)
- Alkali + ammonium salt -> salt + water + ammonia gas (displacement reaction)
-
-
Compounds
- Two or more elements that are chemically combined in a fixed ratio
- Can be broken down into simpler substances or compounds by chemical means like electrolysis
- Homogenous
- Fixed composition
- Fixed MP and BP
- Form with energy change
- Properties different from the elements that make up the compound
