Frequent question: Which of the following is good conductor of electricity in molten state?

The correct answer is Mercury.

Which of the following is conductor of electricity in molten state?

For the ‘conduction of electricity’, the element or compound must have free moving electrons or ions. NaCl is a “good conductor of electricity” in molten state but not is solid state.

Which of the following are good conductor of electricity *?

So, all the elements gold, mercury and tungsten are a good conductor of electricity.

Are metals good conductors of electricity in molten state?

Metal conduct electricity in solid as well as in molten state.

Which type of solid is good conductor in molten state?

d) metallic solid. The ionic solids do not conduct electricity in solid state but it do conducts in molten state because they are bonded by strong ionic bonds in solid state while in molten state the ions are free to move hence conducts electricity.

Is C6H12O6 a good conductor of electricity?

A common example of a nonelectrolyte is glucose, or C6H12O6. Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.

Is molten nacl a good conductor of electricity?

As the motility of individual atoms or molecules in liquid state is far greater than solid, the ions (Na+&Cl−) are free to move and therefore can act as charge carriers. Hence molten sodium chloride is a good conductor of electricity because of free ions.

In which state metals are good conductors of electricity solid state or molten state?

b. Covalent compounds do not conduct electricity even when molten because the resultant mobile particles are neutral molecules. Their movement cannot be used to carry an electric charge. Metals conduct electricity in the solid state because the valence electrons of the atoms generate a mobile “sea” of electrons.

Are metals good conductor of heat?

In metals, there are free electrons which makes the energy transfer easy. Thus, metals are good conductors of heat.

Which metal is good conductor of electricity?

Copper. One of the most commonly used metals to conduct electricity is copper. As a material, copper is pliable, easy to wrap or solder, which makes it the best choice when large amounts of wiring are needed.

Why ionic solid are good conductor in molten state?

Ionic compounds conduct electricity when molten (liquid) or in aqueous solution (dissolved in water), because their ions are free to move from place to place. Ionic compounds cannot conduct electricity when solid, as their ions are held in fixed positions and cannot move.

Which of the following conducts electricity in molten state as well as in solid-state?

Yes. Ionic solids conduct electricity in a molten state but not in solids state. This is because, in ionic compounds, electricity is conducted by ions. In contrast, ions are held together by strong electrostatic forces in a solid-state and are not free to move about within the solid.

Why ionic solids are conductors in molten state?

– Ionic compounds conduct electricity in the molten state because in the molten state, since the electrostatic force of attraction between the oppositely charged ions is overcome due to the heat which is provided to the ionic solid to change it from solid-state to the liquid state.
