|
Name the 2 classes of solids |
Crystalline and Amorphous |
Sorted by type of array |
|
|
Name the 4 categories of Crystalline Solids |
Molecular, Network, Metallic, and Ionic |
Sorted by attraction |
|
|
What are metallic solids made of? Are the conductive? Are they malleable or brittle? |
Cations in a pool of electrons. Yes. Malleable. |
The properties are reliant on the makeup |
|
|
What are Ionic solids made of? High or low Melting Point? Are they malleable or brittle? |
Cations and Anions. High. Brittle. |
The properties are reliant on the makeup |
|
|
What are Network solids made of? High or low Melting Point? Are they malleable or brittle? |
Covalent bonds. Very high. Brittle. |
The properties are reliant on the makeup |
|
|
What are Molecular solids made of? High or low Melting Point? Are they malleable or brittle? |
IM Forces Low Melting point. Brittle if pure. |
The properties are reliant on the makeup |
|
|
Define viscosity |
Resistance to flow |
Viscosity decreases as temperature increases |
|
|
Define surface tension |
Net inward pull of molecules |
Surface tension is high if IM Forces are high |
|
|
Define adhesion |
Forces that bind a substance to a surface |
Part of capillary action |
|
|
Define cohesion |
Forces that bind a substance to itself |
Part of capillary action |
|
|
Define capillary action |
The rise of a liquid in a tube (capillary) |
Combination of adhesion and cohesion |
|
|
Define coordination number |
The number of atoms that a given atom in the solid structure has immediate contact with. |
The coordination number of hexagonal close packed structures is 12 |
|
|
Boyle's Law |
P1V1=P2V2 |
Deals with volume and pressure |
|
|
Charle's Law |
V=Tx |
Deals with volume and temperature |
|
|
Avogadro's Principal |
V(m)=V/n |
Deals with molar volume |
|
|
Avogadro's Law |
V/n |
Deals with volume and moles |
|
|
Ideal Gas Equation |
PV=nRT |
Combination of Boyle, Charles and Avogadro Laws |
|
|
Density of a gas |
M=pRT/P |
|
|
|
Dalton's Law |
P(total)=P1+P2+P3... |
Partial Pressures |
|
|
Molar Fraction |
X(b)=n(b)/n(a)+n(b) |
|
|
|
Define diffusion |
Gradual dispersal of one substance through another |
Like spraying perfume |
|
|
Define effusion |
Escape of a gas through a small hole into a vacuum |
Like a hole in a balloon |
|
|
When are ideal gas laws most accurate? |
At low Pressures and high temperatures |
When are the differences of real gases most significant? |
