Making Useful Products

These flashcards cover key concepts related to the lecture on useful products made by First Nations Australians, chemical reactions, and polymers.

First Nations Australians

Indigenous peoples of Australia who have developed processes to transform natural materials into useful products.

Fermentation

A chemical change brought about by microorganisms that converts starch or sugar into alcohol.

Ethanol

Commonly referred to as ethyl alcohol, produced from the fermentation of sugar.

Polymerization

The chemical reactions that join monomers together to form polymers.

Monomer

A small molecule that can join together with other monomers to form polymers.

Polyvinyl chloride (PVC)

A synthetic polymer made from the monomer vinyl chloride, known for its lightness and rigidity.

Polylactic acid (PLA)

A biodegradable bioplastic made from sugars, compostable in controlled conditions.

Photochromic lenses

Glasses that darken in bright sunlight and lighten in low light conditions.

Condensation reaction

A type of reaction where two different monomers join together and release a water molecule.

Allotropes of carbon

Different structural forms of carbon, including diamond and graphite.
