The ability of a material to regain its original shape after being stretched or bent is known as "____. Rubber is usually chosen as a shock-absorbent material because of this very favourable property. The ability of a material to be stretched without breaking is known as ____. Copper is always chosen for the manufacture of wire because of this very favourable property The ability of a material to be pressed, spread out, or hammered into shape, is known as ____. Lead is used by roofers because of this very favourable mechanical property. ____ is the ability of a material to resist scratching, cutting, and general wear and tear. High-Carbon Steel is used to make lathe and milling machine tools because of this very important mechanical property. Repeatedly hammering and working copper or mild steel at room temperature will cause the metal to become harder and more brittle. The term "____" is used to describe the changes made to the properties of a material when it has been subjected to continued external forces. Glass and Acrylic are examples of materials that will not be bent very much when a force is applied and will break. Mild Steel is an example of a material that can be bent quite a lot before it fails. ____ is the property of a material that determines how much it can be bent before it breaks. A material that can be hit with high forces and not break or bend is said to be very tough. Examples of materials that are tough are Cast Iron and Urea Formaldehyde. Both of these materials have very favorable properties of ____. Carbon Fibre and Aluminium Alloys are used in the car industry because of their ability to retain strength after they have been shaped into body panels. Materials that have high ____ can be stretched and bent without breaking. The ____ of a material is the property that determines how strong it will be when its subjected to a squashing or pressure force. Concrete and Cast iron have this property in abundance. The electrical ____ of material is its ability to conduct electrical current. Copper is a good conductor of electrical current, whereas ceramic is not and is known as an ____ The ____ conductivity of a material is its ability to conduct heat. Glass has a lower thermal ____ than ____, like steel, that is used to make cooking pots. The measure of a material's ability to resist corroding, rusting or oxidizing, in its working environment, is known as ____. Salt, water, weather, fire, heat, air quality, and sunlight are all factors that can contribute to the breakdown of materials. ____ is all to do with how a material corrodes, degrades, and generally breaks down when exposed to environmental conditions.
