Wild card
100
The type of metals fabrication where a polymer (like wax) mold is created and then set in another material. The polymer is melted out leaving a void space that is filled with metal.
What is lost wax casting or investment casting.
100
type(s) of bonding in ceramics
what is a combination of ionic and network covalent
100
The type of polymerization with 100% atom economy
what is addition polymerization
100
The type of composite with multiple layers
what is structural or laminar composites
100
The length of time the pregnant worker was assumed to spend in a trench with contaminated metals
What is 1 year
200
A description of the bonding in metals
what is an electrostatic attractive force between cations and a sea of delocalized electrons.
200
Network forming building block for most ceramic materials
What is Si surrounded by 4 oxygen (tetrahedra)
200
The type of linkage that is present in slime that allows for some sliding, but not full disintegration of the polymer
What are cross links
200
The name(s) of the two distinct phases that are present for a material to be considered a composite
what is the matrix phase and dispersed (or supporting or reinforcing) phase
200
The canned food that had to be "reformulated" when the metal cans no longer corroded into the food
What is pineapple
300
The most common type of corrosion where redox reactions occur randomly over the entire surface
What is uniform attack
300
Processing technique that makes glass stronger and less brittle by inducing residual compressive stresses.
What is tempering.
300
The type of interaction that is broken when polymers are 1. melted and 2. chemically degraded
What is 1. IMF (intermolecular forces) and 2. actual chemical bonds (molecular covalent)
300
The distinction between particle and fiber based composites
What is the equivalency of the axis (particles and equiaxis and fiber have one longer)
300
The sport that saw very rapid improvements due to improved composite technology
What is pole vaulting.
400
Elements that are added to iron to 1. increase hardness and 2. reduce corrosion
What are:
1. carbon
2. chromium
400
The elemental composition of glasses best suited for high temperature purposes
what is borosilicate
400
The additive included in polymers to increase the spacing between the sheets and make them softer and more flexible
What are plasticizers
400
The two additives that resulted in the best survival of drop testing
What are string and cotton balls.
400
A nylon substitute used in WW2 when nylon stockings were turned in for the war effort.
What is gravy
500
Explanation of why transition metal compounds are colored
What is: Ligands or anions near transition metals will impact the d-orbitals differently if the are on-axis or off-axis causing the d-orbitals to split between 2 levels. light is absorbed associated with electrons being promoted from low to high energy levels due to this splitting. The complementary color to the light is observed.
500
The name of the processing technique that allows the glaze to intermix with the ceramic material forming an extra smooth surface with a low porosity (as seen in porcelain)
what is vitrification.
500
The number of distinct condensation polymerization reactions that can be created in a mixture of malic acid and Citric acid.
what is 8?
2 from citric acid by itself (two are the same because symmetric), 2 from malic acid by itself, 2 from citric acid + malic acid when malic acid uses the alcohol part (not 3 because of symmetry) and 2 from the mixture when citric acid uses it's alcohol part
500
Additive to concrete to 1. increase and 2. decrease drying time
what is 1. sugar and 2. calcium chloride
500
The reason Johann Friedrich Bottger was imprisoned by the king of saxony
What is faking alchemy (pretending to convert silver to gold)
