QUESTIONS LIST:

• ceramic: this is a material made from clay or sand. it has high heat resistance.
• galvanizing: also called “plating”. this process coats one type of metal with another that doesn’t rust and protects metal objects from corrosion.
• hardness: how well a material resists scratching. measured as a number between 1-10 on the mohs scale.
• thermoplastic: this type of plastic melts when it is heated up. this means it can be remolded and recycled easily.

• thermoset: this type of plastic has high heat resistance and cannot be recycled once it has been set.
• resilience: a hard hat should have this property so that it does not break when it is hit suddenly by a heavy object.
• corrosion: resistance to _ : a property you would want for something that is exposed to water or salt.
• malleability: metals have this property, which means they can be hammered flat without breaking.
