Answer:
about -269°C, the resistance of mercury drops to Zero!
This discovery of superconductivity by H. Kammerlingh Onnes in 1911 was followed by the observation of other metals which exhibit zero resistivity below a certain critical temperature.

The temperature at which the resistance of mercury is zero is about -269°C.
Explanation:
- The temperature at which the resistance of mercury being zero is known to be as superconductivity of the metal. In 1911, Superconductivity was discovered by H. Kammerlingh Onnes.
- He observed that other metals showed zero resistivity at below a certain temperature.
- The term resistance can be described as the quantity of decreased electricity run through a conductive element. Like the conductors contains the good flow of current has less resistance similarly, bad conductors/insulators have high resistance and not so good flow of current.
- At 4.12K temperature, mercury is let to cool and settle down and the resistance of the mercury turns out be zero which makes it become a superconductor.
