Answer:
conductivity
ductile
Explanation:
Electrical conductivity is the property of a material that quantifies how easily electricity can pass through it. In order for lightning to pass through the material should of high conductivity. The SI unit is siemens per metre (S/m)
Ductility is the property of a material that shows a material's ability to undergo plastic deformation before rupture. Here, the material is pulled into a wire so the material must undergo significant plastic deformation.
I. Bianca is building a lightning rod to safely conduct lightning strikes away from a building. She should choose a material with high: Electrical conductivity.
II. Talia is manufacturing rolls of wire for hanging pictures. She needs a material that is ductile, so that it can easily be pulled into wire without breaking.
The physical and mechanical properties of a material are the properties which can be measured and describes the performance of a material. They include the following;
- Density.
- Melting point.
- Malleability.
- Electrical conductivity.
- Resistivity.
- Ductility.
Conduction refers to the transfer of thermal energy or electric charge as a result of the movement of particles.
Generally, when conduction relates to electric charge, it is referred to as electrical conduction. Thus, electrical conductivity is a measure of the ability of a material or metal to conduct electricity by allowing the flow of electrons and current.
On the other hand, ductility is a property of a material to undergo a change in its physical form through stretching without breaking. Thus, it is the ability of a material to be pliable and flexible.
