Is mercury a best conductor of heat?

Correct Option: B Since mercury is 13+ times as dense as water, a given volume of mercury would carry about 4.4 times as much heat, so mercury is best conductor of heat among the given options. It is the only metal that is liquid at standard conditions for temperature and pressure.

Is mercury element a good 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.

Is mercury a poor conductor of heat?

But in case of mercury and lead, the heat do not get transferred from one particle to another directly as compare to other materials (like gold, silver copper which are good conductors of heat.) Thus, mercury and lead are comparatively poor conductors of heat.

What is the poorest conductor of electricity?

Although metals are supposed to be good conductors of electricity and heat,metals like mercury, lead,alloys of iron and chromium, titanium and stainless steel are poor conductors when compared to silver,copper and gold.

Why is mercury the best conductor of electricity?

Materials which have good mobility of electrons are known as conductors and materials with less mobility of electrons are referred to as insulators. Iron is a better conductor of electricity than mercury because the resistivity of mercury is more than the resistivity of iron.

Why mercury is a bad conductor?

Since high density of mercury, there is no enough room for vibrating mercury atoms. So it can’t be heated easily. So it’s a poor conductor of electricity.

Is mercury an insulator or conductor?

Mercury is a conductor as it can conduct heat well.

Why is mercury good conductor of heat?

We know that mercury has a large value of the coefficient of thermal expansion. Hence, even the smallest change in temperature is evident in the shape of the mercury container. All these factors make mercury a good conductor of heat and this is why it has a large application spectrum especially in measuring devices.
