The Solid State Flashcards
Classifying materials into categories of either a solid or a liquid is primarily on response to….
Stress
For a material to be classified as a solid it must…
withstand indefinitely the stress imposed by its own weight.
under it’s own weight liquid will…
Shear instantaneously.
What exhibits a purely plastic response and will shear instantaneously under it’s own weight…
Liquid
A material that will withstand the stress imposed by it’s own weight is a
Solid.
Many materials response to stress is…
Time dependent.
Which state would you find crystalline or amorphous forms
Solid State.
In the solid state you’re more likely to see forms of
Crystalline or amorphous.
Crystalline solids form most readily where the bond is…
non directional.
Non directional bonding forms…
crystalline solids
Rapid cooling from the liquid state prevents he formation of
crystalline arrays
preventing crystalline arrays is a result of…
rapid cooling from the liquid state.
When the structure of amorphous materials cannot be distinguished easily from from that of corresponding liquid. The solids are referred to as…
Glasses.
Crystallites that are in continuous movement with atoms at the boundaries being lost or gained from other crytallites best describes
liquids
A non-crystalline substance consisting of large molecules or ultramicroscopic particles of one substance dispersed through a second substance is referred to as….
colloids
