Explanation:
The correct options are A and B. Let's understand each option in detail:
a) The metallic conduction is due to the movement of electrons in the metal.
In metallic conduction, metals act as conductors due to the presence of free electrons. In a metal, the valence electrons are not tightly bound to the individual atoms, but instead, they form a "sea" of delocalized electrons that are free to move throughout the metal lattice. When an electric field is applied, these free electrons drift towards the positive terminal, creating an electric current. This movement of electrons is responsible for metallic conduction.
b) The electrolytic conduction is due to the movement of ions in the solutions.
In electrolytic conduction, the movement of ions in a solution or molten state of an ionic compound allows for the conduction of electricity. When an ionic compound is dissolved in a solvent or melted, the ions dissociate and become mobile. Positively charged ions (cations) move towards the negative electrode (cathode), and negatively charged ions (anions) move towards the positive electrode (anode). This movement of ions facilitates the flow of electric current through the electrolyte.
c) The metallic conduction increases with an increase in temperature.
This statement is incorrect. Metallic conduction is not significantly affected by temperature. The movement of electrons in metals is primarily determined by the applied electric field and the presence of free electrons. Temperature has a minimal impact on metallic conduction.
d) The electrolytic conduction decreases with an increase in temperature.
This statement is also incorrect. Temperature does not have a significant effect on electrolytic conduction. The conduction in electrolytes is primarily governed by the movement of ions, which is not strongly influenced by temperature changes.
In conclusion, option A and B are correct. Metallic conduction occurs due to the movement of electrons in metals, while electrolytic conduction occurs due to the movement of ions in solutions or molten ionic compounds. Temperature does not have a substantial effect on either of these conduction processes.
