• hardness

• brittleness

• combustibility

• elasticity

• conductivity

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

• FALSE

Gold can be hammered into flat sheets until the desired shape of jewelry is obtained. This property is called malleability. Example, silver, iron, aluminium.

• TRUE

• FALSE
