1) Elasticity
2) water resistant
3) flexible - 3Fossil FuelsCoal, Oil & Gas
Made from dead matter compressed under high pressure eg. sedimentary rock - 4Synthetic Materials vs. NaturalSynthetic = Man Made eg. Acrylic, Polyester (anything with Poly)
Natural = From nature eg. cotton, wool, leather. - 5Properties of MaterialsBrittle - doesn't deform before it breaks.
tough - strong and doesn't change shape
Stiff - needs a lot of force to change shape.
Flexible - Don't need much force to change shape.
Ductile - twist it into wires.
Malleable - can be bent into new shapes without breaking. - 6Fractional Distillation of Crude Oil
- 7Changing PolymersCrosslinking - stronger because more bonds.
Increasing Chain Length - stronger because more friction & density.
Plasticizer - weaker so it is more flexible.
Crystallization - stronger because forces between molecules are closer. - 8Molecule Diagrams
