Which substance is a good conductor of electricity in both solid and liquid phases? – Quora. Any metal meets this requirement. All metals are good electrical conductors in their solid or liquid state.
Which substance will conduct electricity in both solid and liquid phase?
5) Which substance will conduct electricity in both the solid phase and the liquid phase? 7) Which of the following solid substances contains positive ions immersed in a sea of mobile electrons?
…
| Substance A | Substance B | |
|---|---|---|
| Solubility in Water | nearly insoluble | soluble |
| Hardness | soft, waxy crystals | hard crystals |
What type of substance is a good conductor of electricity in all phases?
Copper is considered to be a conductor because it “conducts” the electron current or flow of electrons fairly easily. Most metals are considered to be good conductors of electrical current. Copper is just one of the more popular materials that is used for conductors.
Which of the following is a good conductor of electricity in solid as well as liquid state?
Graphite is the only non-metal which is a good conductor of electricity.
Can conduct electricity in the solid and liquid phase?
Ionics solids are held together by the electrostatic attraction between oppositely charged ions. … Since the ions cannot move, ionic solids are non-conductors of electricity. When the solid is melted to a liquid, however, the ions are free to migrate. Therefore, ionic liquids are good conductors of electric current.
Which type of substance can conduct electricity in the liquid phase but not the solid phase?
Which type of substance can conduct electricity in the liquid phase but NOT in the solid phase? An ionic compound.
Which substance is a good conductor of electricity when solid?
All solid metals have some conductive properties with gold and copper being among some of the best. Some basically non-metalic materials can also conduct electricity in solid form, such as graphite and silicon. Compounds of metals do not conduct electricity as a solid, but metals are good conductors of electricity.
What is meant by good conductor of electricity?
Good conductors are those materials which allow electricity to pass through them easily. Bad conductors are those materials which do not allow electricity to pass through them easily.
What are the best conductor of electricity?
What Metal is the Best Conductor of Electricity?
- Silver. The best conductor of electricity is pure silver, but to no surprise, it is not one of the most commonly used metals to conduct electricity. …
- Copper. One of the most commonly used metals to conduct electricity is copper. …
- Aluminum.
Which substance is good conductor of electricity at room temperature?
The best electrical conductor, under conditions of ordinary temperature and pressure, is the metallic element silver. Silver is not always an ideal choice as a material, however, because it is expensive and susceptible to tarnishing, and the oxide layer known as tarnish is not conductive.
Is ether a good conductor of heat?
Solids are generally very good conductors of heat. Silver and copper are excellent conductors of both heat and electricity.
…

| Ether | 0.130 |
Is alcohol a good conductor of electricity?
No, for a solution to conduct electricity, presence of free ions is necessary, hence alcohol, which doesn’t ionise is a bad conductor of electricity.
Which substance conducts electricity in the liquid 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.
What substance conducts electricity in the liquid state but is a poor conductor in the solid state?
In the solid state, ionic compounds such as sodium chloride have their ions fixed in position and therefore these ions cannot move so solid ionic compounds cannot conduct electricity. However in the molten state, ions in ionic compounds are free to flow and therefore molten sodium chloride can conduct electricity.
