Card Set Information
a material that returns to its original shape and size after a deforming force is removed.
a compound produced by polymerisation, capable of being moulded into various shapes or drawn into filaments and used as textile fibres
a long thin thread or filament
Melting point (mp)
The temperature at which a solid becomes a liquid (melts). It is the same temperature as the freezing point.
a measure of resistance of a solid to a pulling or stretching force
a measure of resistance to squeezing or crushing forces
a measure of the resistance of a solid to bending forces
a measure of resistance to change in shape of a solid, for example by scratching or by impact
the mass of a substance per unit volume
a theoretical value that could be found if measurements could be made without error
black substance extracted from earth, from which petrol and many other products are made
Organic compounds that contain carbon and hydrogen only
A class of hydrocarbons in which the atoms are connected only by single bonds.
the separation of the components in a liquid mixture into fractions which differ in boiling points.
the change state from a gas to a liquid
a specific section of a product formed by fractional distillation
A very large molecule that is composed of many small, repeating structural units.
The small organic molecule that is repeated many times in a polymer.
chemical process that combines monomers to form a polymer
a solid material with atoms, molecules or ions arranged in a regular repeating pattern
a substance used to soften plastics and increse flexibility
plastic with a shape that can be changed by heating
bonds that link one polymer chain to another
plastic with a shape that becomes perminant after heating or cooling
a unit of length 1,000000000 times smaller than a metre
a very tiny particle, whose size can be measured in nanometers
particles or structures between 1 and 100nm in size, containing a few hundred atoms
a carbon molecule in the form of a cylinder
A substance that increases the rate of reaction by lowering the activation energy.
material consisting of a mixture of other materials
