1.-Each object has its own set of __________ that makes it suitable for different uses.

• Plasticity

• Properties

• Hardness

2.-This refers to an object’s resistance to friction, or being scratched.

• Hardness

• Strenght

• Toughness

3.- This is an object’s ability to resist cracking when a force is applied to it, such as when it is bent.

• Strenght

• Toughness

• Hardness

4.-This is determined by the quantity of force needed to make a material deform when it is pushed or pulled.

• Toughness

• Hardness

• Strenght

5.-This describes an object’s ability to deform without breaking.

• Elasticity

• Plasticity

• Absorbency

6.- This is an object’s ability to return to its original shape after a force has been applied to it.

• Absorbency

• Plasticity

• Elasticity

7.- This refers to an object’s ability to soak up a liquid but can also refer to an object’s ability to take in energy, such as heat or radiation.

• Absorbency

• Plasticity

• Elasticity

8.- It's hard and strong because it does not scratch easily. It doesn't deform easily, and also is transparent, which makes it suitable to use in light fixtures, windows and food jars.

• Glass

• Elasticity

• Metals

9.- They are resistant to scratching, cracking and deformation under heavy loads. Although some of them are prone to rusting if they are in contact with oxygen and water regularly.

• Absorbency

• Metals

• Glass

10.- _________are materials that have been made from crude oil, a type of fossil fuel. They are used to package food and drinks, to make garbage bags, for parts in televisions and computers, and in stationery, clothing and light fixtures.

• Woods
