Name three different polymers?
Plastic, Rubber, DNA, Starch, Cellulose
True or False: A composite material is made of two or more materials combined together?
True - A composite material is always two or more materials combined together.
What does Carbon Dioxide cause?
Carbon Dioxide contributes to the greenhouse effect causing global warming and climate change.
Where does the majority of waste go in the UK?
The majority of waste ends up in landfill where it destroys the environment and plant life.
Name three properties of Ceramics?
Hard, Stiff, Strong when compressed, Brittle, High melting point, Good insulators or heat, Good Insulators of electricity, Very Unreactive.
What are Polymers made of?
Polymers are made of smaller molecules called monomers which are stuck together by bonds.
True or False: A composite material only has the properties of one of the materials it is made from?
False: A composite material has a combination of the properties of the materials it is made from.
True or False: Sulfur dioxide causes acid rain?
True - Sulfur Dioixde mixes with water vapour in clouds to form acid rain which damages buildings and plants.
True or False: Glass can be recycled easily?
True - Glass is easily recycled by heating it up and melting it and then forming new glass products.
Give three uses for Ceramics?
Pottery and Tableware: Bowls, plates, mugs and vases.
Building Materials: Bricks, tiles, and toilets.
Glass: Anything made of glass.
Name four properties of Plastic?
Strong, Hardwearing, Durable, Flexible, Waterproof, Unreactive, Electrical Insulator, Thermal Insulator.
What is concrete made from?
Cement, Sand, Crushed Rocks and Water.
True or False: Carbon Monoxide is safe to breathe in?
False - Carbon Monoxide is poisonous to humans and most animals.
True or False: All plastic can be recycled?
False - There are some plastics which cannot be recycled and have to go to landfill.
True or False: Ceramics are very hard due to the lattice structure of crystals formed when they cool down.
True - these strong bonds in the lattice make ceramics hard.
Name the monomer found in Poly(Propene)?
Propene
What is a composite material?
A composite material is a combination of two or more different materials with some of the properties of each.
