CHEM II: Solids!

What is solid to gas called?

sublimation

What is gas to solid called

deposition

What is Heat of Fusion?

amount of energy required to melt one mole of the solid

What is an amorphous solid?

constituent particles are randomly arranged and have no ordered long-range structure

What are crystalline solids?

constituent particles have an ordered arrangement extending over a long range; ex: ionic solids, molecular solids, covalent network solids, metallic solids

Ionic solids:

particles are ions ordered in a regular 3D arrangement and held together by ionic bonds

Molecular solids:

particles are molecules held together by intermolecular forces

Covalent network solids:

particles are atoms linked together by covalent bonds into a giant array; ex: carbon

Metallic solids:

particles are metal atoms whose crystals have metallic properties such as electrical conductivity

What’s a phase diagram and its components?

it describes the different states and state changes that occur at various temperature-pressure conditions; areas represent states, lines represent state changes, triple point is the temperature/pressure condition where all three states exist simultaneously
