Ductility is the property that describes the ability of a material to be stretched into a wire without breaking. Materials with high ductility, such as copper, can be drawn into thin wires, making them useful for electrical wiring and similar applications.

The correct answer is "Hardness." Hardness is a material property that measures how resistant a material is to scratching, indentation, or abrasion. Materials with higher hardness are more difficult to scratch or indent.

This statement is True. Toughness is the ability of a material to absorb energy and plastically deform without fracturing. Tough materials can withstand impacts and are less likely to break suddenly.

Copper is most likely to be used where electrical conductivity is important because it is an excellent conductor of electricity. Materials like balsa, acrylic, and MDF do not conduct electricity well.

Bending the materials to see if they snap is the most suitable test for brittleness. Brittle materials break or snap when bent, while ductile or malleable materials may bend or deform without breaking.

The correct answer is "malleability." Malleability is the property of a material that enables it to be hammered or rolled into thin sheets without breaking.

Fatigue resistance is the property being tested when a material is repeatedly bent until it breaks. Fatigue resistance measures how well a material can withstand repeated cycles of stress before failing.

According to the chart, Mild Steel has the highest hardness value among the four materials tested. Therefore, Mild Steel is the hardest.

a) Elasticity - 2. Ability to bend and return to original shape
b) Durability - 1. Ability to withstand wear, pressure, or damage
c) Plasticity - 3. Ability to permanently change shape

According to the chart, Balsa absorbs the most water in one hour, indicating it is the most permeable material among those tested.
