What characteristics do ionic liquids have?
Such liquids have high density, good electrical conductivity and become solid as temperature decreases from their melting point.
What is the difference between thermal and electric conductivity?
Electrical conductivity is flow of electrons between two different points having different electric potentials. Thermal conductivity is flow of electrons between two different points having different temperatures. Electrical Conductivity in solids, is purely based on number of free electrons (number of free electrons and holes in semiconductors). But thermal conductivity is based on number of free electrons and also phonons. Electrical conductivity in liquids and gases is also depends on number of free electrons but thermal conductivity in liquids and gases is because of molecular collision.
What shape and volume properties do gases and liquids and solids have?
Mass and volume
What would i do to help me determine if something is metal?
Check the conductivity. Check whether it is lustrous. Check whether it is malleable.
My conductivity meter is giving me inconsistent readings. How can I tell whether it's broken, or if I'm using it wrong?
If you conductivity meter is giving you inconsistent readings, it should be checked. You can purchase conductivity standards at your dealer or distributor to check it yourself. You should also check the battery to see if it needs to be replaced.
What has the author Olin Freeman Tower written?
Olin Freeman Tower has written: 'A course of qualitative chemical analysis of inorganic substances' -- subject(s): Analytic Chemistry, Chemistry, Analytic, Qualitative 'The conductivity of liquids' -- subject(s): Electrolytes, Conductivity
Are liquid good insulators of heat?
It will depend on the specific heat, and conductivity of the material in question. energy does not care what state a matter is in. in general, no, liquids allow the molecules to move about, and will transfer the heat more quickly than a solid, however, consider aluminum, though a solid, it transfers heat quickly, while some liquids might be slower. As I said, depends on conductivity an specific heat.
How can you tell if an object is an insulator?
Different combinations of elements form different types of bonds. Ionic or covalent bonds in solid materials result in materials that have low electrical conductivity (hence are good insulators). Metallic bonds are the kind that produce high conductivity. Liquids may be electrically conductive to the extent that they contain dissociated ions. Liquids that are non polar and contain no ions will be good insulators.
What is soil conductivity?
Soil conductivity is the conductivity of the soil. Thank you
What is the valve on a pump to keep liquids from reentering the pump?
check valve
What properties of liquids will affect its conductivity electricity?
Electricity is conducted well in substances that have lots of free electrons, or other free charge carriers. That is, charge carriers that are free to move around.
How do i confirm that this water is demineralized water?
The commonest test is to check the electrical conductivity between two electrodes. Pure water has very poor conductivity, but the conductivity improves as more ions are dissolved in it. Sea water has a conductivity of around 5 S/m (Siemens per metre) Drinking water has a conductivity of 0.005 - 0.05 S/m . Ultra-pure water has a much lower conductivity of 5.5 x 10-6 S/m - a million times smaller than that of sea water.
