Malleability
- ability of metals to be flattened into sheets without breaking
Ductility
- ability of metals to be drawn into wires
Elasticity
- ability of an object to be stretched and then return to its original shape
Solubility
- amount of solute that be dissolved in a given amount of solvent at any given temperature
surface tension
- property of liquid to draw the surface molecules into the body of a liquid and reduces its surface area
Viscosity
- resistance of fluid to flow
Capillarity
- ability of liquids to rise through tubes
Luster
- ability of metals to reflect light
hardness
- ability to withstand being scratched, cut or dented
brittleness
- ability of metals to break suddenly under tension
porosity
- capacity of some materials to absorb or release liquids or gases
More porous material, less
dense
permeability
- allow water/gas to attract with each other
cohesion
- 2 or more same molecules attract
adhesion
- 2 or more different molecules attract
tenacity
- resistance of material to breakage
specific gravity
- ration of mineral's weight to the weight of an equal volume of water
magnetism
- ability to be attracted to magnet
MAGNETISM
paramagnetic
- weakly attracted to a magnetic field due to unpaired electrons
MAGNETISM
Diamagneitc
repelled by a magnetic field
MAGNETISM
Ferromagnetic
- strongly attracted to an external magnetic field
