Flashcards in Different States of Matter Deck (6)
what are the two general forms of solids and what makes them different?
crystalline: regular and orderly array
amorphus: disordered network of strongly bonded atoms
what are the different types of solids and what makes them different?
atomic: consists of invididual atoms packed in a regular crystalline array with relatively weak dispersion forces between the atoms. only the noble gases form atomic solids at low temp
metallic: atomis with a low ist ionisation energy form similar array as atomic, valence electrons form a delocalised cloud of electrons
ionic: formed by ions
molecular: molecules held together by intermolecular forces
network covalent: atoms linked by strong covalent bonds in an extensive 3 dimensional network through the whole solid
what are some properties of solids?
what are some properties of liquids?
-kinetic energy of molecules is comparable to intermoleculer forces
-able to flow
-no fixed shape, high density, has a surface and surface tension
-viscosity that can be explained by intermoleculer forces
what is viscosity?
the measure of a liquids resistance to flow
