What is value of electrical conductivity of fuel oil?
The electrical conductivity of fuel oil can vary depending on its composition, but typically falls in the range of 10-200 picosiemens per meter (pS/m). This measurement may also be influenced by factors such as temperature, impurities, and additives present in the fuel oil.
What is the electrical conductivity of paper?
The electrical conductivity of paper is generally low, as it is primarily composed of cellulose fibers, which are poor conductors of electricity. However, the conductivity can vary depending on factors such as moisture content, additives, and the type of paper. In humid conditions, paper can absorb moisture, increasing its conductivity. In general, paper is considered an insulator rather than a conductor.
What is the conductivity of sea water?
The conductivity of seawater is typically around 3.5 to 5.8 Siemens per meter (S/m) at a temperature of 25 degrees Celsius. This conductivity is primarily due to the presence of dissolved salts, such as sodium and chloride ions, which allow the water to conduct electricity. The conductivity of seawater can vary based on factors such as temperature, salinity, and the presence of other dissolved substances. Conductivity is an important parameter in oceanography and environmental monitoring to assess the health and composition of marine ecosystems.
Does river water conduct electricity?
Yes, river water can conduct electricity, but its conductivity depends on the presence of dissolved ions and minerals. Freshwater typically has lower conductivity than seawater due to fewer dissolved salts. Factors such as pollution, sediment, and organic matter can increase the conductivity of river water. Overall, while river water is not a strong conductor, it can still carry electrical currents under certain conditions.
What property determines the choice of material that is used for the inside of an electrical wire and the material that is used for the outside of the wire?
The most important property is the conductivity of the material under consideration. A high conductivity is needed for the inside, and a very low conductivity for the outside. Only after this can we consider other factors, such as cost, strength, toxicity, flammability, flexibility, corrosion resistance and ease of making and shaping.
How does the gas electrical conductivity vary with different factors?
The electrical conductivity of gas can vary based on factors such as temperature, pressure, and the presence of impurities. Generally, higher temperatures and pressures can increase conductivity, while impurities can either increase or decrease conductivity depending on their nature.
What factor should change in electrical conductivity of metals and non metals?
In metals, electrical conductivity increases with higher number of free electrons, which can be influenced by factors like temperature and impurities. In non-metals, electrical conductivity is generally lower due to lack of free electrons, but can increase with doping or introduction of impurities.
What is value of electrical conductivity of fuel oil?
The electrical conductivity of fuel oil can vary depending on its composition, but typically falls in the range of 10-200 picosiemens per meter (pS/m). This measurement may also be influenced by factors such as temperature, impurities, and additives present in the fuel oil.
What are the characteristics of a good conductor semiconductor and insulator?
A good conductor has high electrical conductivity, allowing electric current to flow easily. A semiconductor has moderate electrical conductivity, which can be controlled using external factors like temperature or doping. An insulator has very low electrical conductivity, preventing the flow of electric current.

In general, paper is considered an insulator rather than a conductor.
What is soil conductivity?
Soil conductivity is a measure of a soil's ability to conduct an electrical current. It is influenced by factors such as soil moisture content, soil texture, and the presence of salts and minerals. Higher soil conductivity levels can indicate higher levels of salinity, which can impact plant growth.
Is electrical conductivity physical change or chemical?
Yes

How thick is a lightning bolt and what factors determine its width?
A lightning bolt is about the width of a human thumb, typically around 1 inch (2.5 centimeters) thick. The factors that determine the width of a lightning bolt include the amount of electrical charge, the distance it travels, and the conductivity of the air it passes through.
Does river water conduct electricity?
Yes, river water can conduct electricity, but its conductivity depends on the presence of dissolved ions and minerals. Freshwater typically has lower conductivity than seawater due to fewer dissolved salts. Factors such as pollution, sediment, and organic matter can increase the conductivity of river water. Overall, while river water is not a strong conductor, it can still carry electrical currents under certain conditions.
What are the factors that effects the conductivity of pencil lead?
The factors that affect the conductivity of pencil lead include the quality of the graphite in the lead, the hardness of the pencil lead, and any impurities present in the lead. Higher quality graphite and softer leads typically have higher conductivity, while impurities can decrease conductivity. Additionally, the pressure applied when writing or drawing with the pencil can also impact conductivity.
What thermal conductivity of asbestos power?
The thermal conductivity of asbestos powder can vary depending on factors such as the type of asbestos and its form. Typically, asbestos has a thermal conductivity ranging from 0.03 to 0.2 W/(m·K), which means it is a poor conductor of heat. It was commonly used as insulation due to its low thermal conductivity properties.
