Chem Lec Flashcards
Common used class of engineering material
Metal
Molecules formed by long chains of repeating monomer units
Polymer
Polymers are classified as
Thermoplastic polymers, thermosetting polymers, and elastomers
May consist of metallic or nonmetallic elements
Ceramics
Classification of ceramics
Glasses, cements, clay products, refractories, and abrasives
Generally have excellent corrosion and wear resistance
Ceramics
Is a material in which one or more mutually insoluble materials are mixed or bonded together.
Composite
Have regular ordered arrays of components held together by uniform intermolecular forces
Crystalline Solids
Regular repeating three dimensional structure
Crystal lattice
Are chemical substances or materials that are manufactured and used at a very small scale.
Nanomaterials
Refers to the surrounding of an object or organism
Environment
Focuses on the presence and impact of chemical in soil
Environmental chemistry
Air surrounds the earth and extends out for about 1,000 miles, gradually fading into space at that point
Atmosphere
Being with the lower level
Troposphere
Which the chemistry of the Earth’s atmosphere and that of other planets is studied
Atmospheric chemistry
