  • 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
  • FALSE
