What else can I help you with?
Lower salinity increases the conductivity of sea water?
yes it does
What are the differences in conductivity between steel and copper?
Steel has lower conductivity compared to copper. Copper is a better conductor of electricity than steel due to its higher conductivity properties.
How does the concentration of NaCl affect the conductivity of a solution?
The concentration of NaCl in a solution directly affects its conductivity. Higher concentrations of NaCl result in higher conductivity, as more ions are present to carry electric current. Conversely, lower concentrations of NaCl lead to lower conductivity due to fewer ions available to conduct electricity.
How can the resistivity of water be measured?
The resistivity of water can be measured by using a device called a conductivity meter, which measures the electrical conductivity of the water. The higher the electrical conductivity, the lower the resistivity of the water.
What is the relationship between the purity of water and its conductivity?
The purity of water is inversely related to its conductivity. Higher purity water has lower conductivity because impurities in water, such as minerals and ions, increase conductivity by allowing the flow of electric current.
What is the effect of porosity on heat conductivity?
Porosity decreases the heat conductivity of a material because the void spaces act as barriers to the flow of heat. This is because air or other insulating gases within the pores have lower thermal conductivity compared to the solid material. As a result, materials with high porosity generally exhibit lower heat conductivity.
Why alloys have low conductivity?
Alloys generally have lower conductivity compared to pure metals because the presence of different elements in the alloy can disrupt the flow of electrons, leading to increased resistance. These impurities and disturbances in the lattice structure can hinder the movement of electrons through the material, resulting in lower overall conductivity.
What large materials are good thermal conductors and good electrical conductors?
from wiedemann franz law we know that thermal conductivity/electrical conductivity=constant that is sigma inv. proportional to k thus a material having large electrical conductivity has low thermal conductivity and moreover we know R=pL/A p=RA/L 1/P=L/RA i.e lower area means greater conductivity(electrical) and lower thermal conductivity
What is relative conductivity?
Relative conductivity refers to the ability of a material to conduct electricity compared to a standard material. It is commonly used to compare the conductivity of different materials based on their relative values. Materials with higher relative conductivity values exhibit better electrical conductivity than materials with lower relative conductivity values.
What is the rate at which a substance transfers heat?
conductivity
Can a pencil conduct energy?
Yes, a pencil can conduct energy to some extent, particularly if it contains graphite. Graphite is a form of carbon that has some conductivity, allowing it to conduct a small amount of electricity. However, the conductivity of a pencil is significantly lower than that of metals or other materials specifically designed for conducting energy.
What is the electrical conductivity for boron?
Boron is a semiconductor, so its electrical conductivity is lower than that of a metal but higher than that of an insulator. Boron's conductivity can be altered by adding impurities to create p-type or n-type semiconductors.
