Question

State whether given statement is True or False
A vegetable oil is a good conductor of electricity.
A. True
B. False

Answer 1

Hint:An ion is identical to a molecule, but it has an electrical charge since the number of protons does not match the number of electrons.An electron, which has a net electrical charge, is an atom or molecule. Since the electron's charge (considered negative by convention) is equal to and opposed to that of the proton (considered positive by convention), regardless of the total number of electrons being unequal to its total number of protons, the net charge of an ion is non-zero. A cation, with less electrons than protons, is a positively charged ion, while an anion is negatively charged, with more electrons than protons. Cations and anions bind each other and readily form ionic compounds because of their opposite electric charges.

Complete answer:
-An electrically charged atom or a group of atoms created by the loss or gain of one or more electrons, as a cation (positive ion) produced by the loss of electrons and attracted to the electrolyzed cathode, or as an anion (negative ion) produced by the gain of electrons and attracted to the anode. The valency of an ion is proportional to the sum of electrons lost or obtained and is shown by a cation plus sign and an anion minus sign.
-The flow of positive ions in one direction, along with the movement of negative ions in the other direction, is usually the current in gases and liquids. Its direction is generally taken to be that of the positive charge carrier to treat the ultimate effect of the current. A negative charge current going in the same direction is equal to a positive charge moving in the traditional direction of the same magnitude and must be included as a contribution to the overall current.Example: The passage of holes in the conventional direction and of electrons in the opposite direction is the current in semiconductors.
-Electrical movement relies on the ions present in the material. If there are no ions in it, that is, if the substance is an insulator or a weak conductor, vegetable oil conducts limited electricity under normal conditions. If they contain some water or salts or other impurities, they work better. Vegetable oil does not have electrons, so it is unable to conduct electricity.

Hence, vegetable oil is not a very good conductor. Hence, the statement is false and option (B) is the correct answer.

Note:Oil is an insulator, i.e., a weak electricity conductor. But it is a strong heat conductor. Conductivity, however, is not only used for electricity. It is used for heat as well. Some substances are fine electricity conductors, but vice versa, a weak conductor or heat insulator.
