What terms describe a substance that has a low melting point and poor electrical conductivity?
covalent and molecular
What else can I help you with?
Which type of bonding is characteristic of a substance that has a high melting point and electrical conductivity only in the liquid phase?
The substance would likely exhibit metallic bonding. Metallic bonding is responsible for high melting points due to strong bonding between metal atoms. Electrical conductivity in the liquid phase occurs because the metal atoms are mobile and able to carry electrical charges.
What do physical properties describe about a substance?
Physical properties describe the characteristics of a substance that can be observed or measured without changing the composition of the substance, such as color, density, melting point, boiling point, and conductivity. These properties provide information about how a substance behaves under different conditions.
Is iron a metallic substance?
It is NOT just a metallic substance, but a METAL!!!!!
What arr some of the physical properties of a pure substance?
Physical properties of a pure substance include color, melting point, boiling point, density, solubility, and conductivity. These properties can be used to identify and characterize the substance.
A property not associated with metal are electric conductivity?
Low Melting Point. Most metals have high melting point and are solids at room temperature.
What do you considered a physical property of a substance?
Examples of physical properties: density, mass, melting point, electrical conductivity, hardness, etc.Physical properties are measurable characteristics.

What are three examples of physical property?
Three examples of physical properties are color, density, and melting point. These properties can be observed and measured without changing the composition of the substance.
What are 6 physical properties a physical substance may posses?
Examples: density, thermal conductivity, electrical resistivity, thermal expansion, ductility, malleability, hardness etc.
How can physical properties be used to identify?
Measuring: the hardness, thermal conductivity, electrical conductivity, refractive index, melting point, etc.
Electrical contact materials used in switches brushes and relays must possess which thermal conductivity and melting point?
Electrical contact materials used in switches brushes and relays must possess high thermal conductivity and high melting point.High thermal conductivity dissipates heat effectively and high melting point is to avoid fusing in case of accidental overheating.
What are several physical properties?
Physical properties of matter include characteristics such as color, texture, density, melting point, boiling point, and conductivity. These properties can be observed or measured without changing the chemical composition of the substance.
Is high melting point a reason of using copper to make electrical wires?
The most important is the high electrical conductivity of copper.
