Copper and gold are different metal elements with different properties. The thermal conductivity of gold is 318W/mK, whereas the thermal conductivity of copper is slightly higher at 401W/mK. The electrical conductivity of copper is slightly higher at 5.96 x10 7 S/m than gold which is 4.11×10 7 S/m.

Why is gold used instead of copper
Gold certainly has good conductivity, which means that electricity can easily pass through it in combat. Copper, silver, and aluminum are too electrically conductive, but gold has improved electrical conductivity. As a consequence, it is an ideal material for making electrical components like the ones we mentioned earlier.
Are gold and copper good conductors
The Gold Gold line is flexible: it can be wrapped with the thinnest thread. Gold is a conductor of heat and electricity. Copper and therefore silver are the best conductors, unfortunately gold compounds last longer than both as they do tarnish.
Is gold good at conducting electricity
At best, gold is considered an electrical conductor. Unlike other metals, gold does not necessarily tarnish when exposed to air. On the other hand, metals such as steel or copper wear out when exposed to oxygen for a long time. In addition, it remains a driver for a long time.

What happens when copper powder is heated in air * blue colored copper sulphate is formed black colored copper oxide is formed blue colored copper nitrate is formed pale green copper carbonate is formed
When copper powder is heated on a porcelain plate, the surface of the copper additive is covered with a black substance due to the formation of copper oxide during surface oxidation. The black color is due to the formation of this copper oxide because the copper simply comes into contact with air.
What happens when dilute sulphuric acid is poured on a copper plate copper sulphate formed copper chloride formed hydrogen sulphide formed copper sulphide formed
Answer: Answer: Office Assistant does not react with dilute sulfuric acid. No, the reaction occurs as soon as dilute sulfuric acid is always poured onto a copper plate.
What is the difference between thermal conductivity and heat conductivity
Thermal conductivity is the ability to transfer heat, while specific heat capacity is the ability to hold a given amount of hot air. All conductors have a relatively lower specific heat, but non-conductors have a high specific heat.
What is the ratio of thermal conductivity to electrical conductivity
In physics, the Wiedemann-Franz law states that the ratio of the contribution of tobacco between the thermal conductivity (?) and electrical conductivity (?) of the metal is proportional at any temperature (T).
Why molar conductivity increases with dilution but conductivity decreases with dilution
When my solution is diluted, the number of available ions per unit volume decreases again, reducing this conductivity. The molar conductivity of all weak and strong electrolytes increases, indicating a decrease in concentration or even dilution. … These active ions increase the conductivity.
How does the conductivity and molar conductivity varies with concentration
The selected conductivity and molar conductivity vary with electrolyte concentration. The conductivity of an electrolyte clearly decreases with decreasing concentration in lean and strong electrolytes, and the molar conductivity decreases with increasing concentration as concentration increases.
What is limiting molar conductivity why there is steep rise in the molar conductivity of weak electrolyte on dilution
As the concentration approaches zero, the most significant molar conductance is known as minimizing molar conductance. The alternation of the film with dilution occurs due to an increase in the degree of dissociation, with a sharp increase in the number of ions contained in the total volume of the yield containing 1 mol associated with the Am electrolyte.
