A substance is tested and is found to have the following physical properties high electrical conductivity malleability high luster The substance is most likely a?
The substance is most likely a metal. Metals are characterized by high electrical conductivity, malleability, and a shiny appearance, or high luster. These properties make metals suitable for various applications, including electrical wiring and structural materials. Common examples include copper, aluminum, and gold.
What else can I help you with?
What All matter has three characteristics?
All matter has the following three characteristics: mass, volume, and length. These are the extensive properties. Mass also has intensive properties: density, color, conductivity, malleability, and luster.
What properties of copper make it ideal for use in electrical wires and for lining cooking pots?
Following are the properties of copper make it ideal for use in electrical wires and for lining cooking pots:- 1) Ductility 2) Conductivity 3) Low resistance 4) Low cost
Alloys are commonly used in manufacturing. Which of the following is not a reason to use an alloy instead a pure metal?
Alloys are not used instead of pure metals when the desired properties of the pure metal are specific, such as in cases where high electrical conductivity or chemical purity is required.
Which is the following terms means that metals can be pulled into thin strands or wires?
Malleability
Which of the following are electrical hazards?
There are three main types of electrical hazards: Shock, Arc Flash and Blast .
Which of the following properties can be attributed to the fact that the electrons are delocalized and are able to move freely in metallic crystals?
High electrical conductivity, high thermal conductivity, and malleability can be attributed to the delocalized electrons in metallic crystals.
Mobile electrons in the metallic bond are responsible for?
all the following luster, thermal and electrical conductivity (:
What All matter has three characteristics?
All matter has the following three characteristics: mass, volume, and length. These are the extensive properties. Mass also has intensive properties: density, color, conductivity, malleability, and luster.
What if the following is characteristic of a metallic bond?
In a metallic bond, atoms share their electrons freely, allowing them to move throughout the structure and creating a "sea of electrons." This shared electron cloud gives metals their unique properties such as high electrical and thermal conductivity, malleability, and ductility. The presence of delocalized electrons is a key characteristic of metallic bonding.

Which is the following terms means that metals can be pulled into thin strands or wires?
Malleability
Which one of the following does not affect the electrical resistance of a body?
The color of the body does not affect its electrical resistance. Electrical resistance is determined by factors such as the material, dimensions, and temperature of the body. The color of an object is related to its appearance and does not have a direct impact on its electrical properties.
Which if the following would have the best thermal insulation properties?
A material with low thermal conductivity, such as aerogel, is known to have the best thermal insulation properties. It is lightweight, highly porous, and has excellent heat resistance, making it an efficient insulator.
Which of the following are properties of MR contrast agents?
Which of the following are properties of MR contrast agents
Is silver oxide conductive?
Silver is the best conductor of electricity. Following this is copper, gold and then aluminium.
Which of the following can NOT be used to store an electrical charge?
Wood is not a material that can be used to store an electrical charge. Materials such as capacitors, batteries, and supercapacitors are commonly used for this purpose due to their ability to hold and release electrical energy. Wood is an insulator and does not have the conductive properties needed to store a charge.
