Hardness is the ability of material to be rigid pressure that may cause deformation or change in its shape. Example, metal and wood.
TRUE
FALSE
Not all hard materials are unbreakable, though there are solid materials that when subjected to high stress or pressure, crumble or break easily. Example, glass and porcelain.
TRUE
FALSE
Elasticity is the ability of a material to be bent without breaking. Example, metal wires and plastic strings.
TRUE
FALSE
Elasticity is the ability of a material to be stretched and then return to its original shape after. Example, rubber band.
TRUE
