Why is mercury a good conductor?
It also has an ample value for thermal conductivity. Along with all this, it also holds a very low boiling point which makes it suitable to measure higher values of temperature. All these factors make mercury a good conductor of heat and this is why it has a large application spectrum especially in measuring devices.
Is mercury a good electrical conductor?
Silver is a poor conductor of electricity while mercury is a very good conductor.
Why liquid is a good conductor of electricity?
Solution: Liquid conduct electricity because they have free ions as in acids, bases and salts being dissolved in water.
Why is mercury the best conductor of heat?
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 liquid mercury good conductor of heat?
Mercury, a liquid metal, is a good conductor of heat.
Is mercury an electrical insulator?
The correct answer is Mercury. Mercury is NOT an insulator. Insulators are material that does not conduct electricity.
What is the best liquid conductor?
Mercury
Solution: Mercury is the good conductor of heat.
What kind of liquid is the best conductor Why?
According to the thermal properties of matter, mercury is the only liquid good conductor of heat. That is why it is also used in a mercury thermometer. We know that most metals are good conductors of heat as solid at room temperature.
Is mercury a good or bad conductor of heat?
Mercury is a bad conductor of heat.
Why mercury is good conductor of heat but bad conductor of electricity?
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.
Why is mercury a good conductor of heat and not water?
We know that most metals are good conductors of heat as solid at room temperature. But mercury is the only good conductor of heat in a liquid state due to its high coefficient of expansion. One more property of mercury that is its high boiling point makes it suitable for measuring high temperatures.
Does mercury conduct heat?
Mercury is a heavy, silvery-white liquid metal. Compared to other metals, it is a poor conductor of heat, but a fair conductor of electricity.
Which is best conductor of heat water or mercury?
Mercury has the highest thermal conductivity of 8. 30W/(m−K) among given options, so it is the best conductor of heat.
Why mercury is a poor conductor?
Mercury is a poor conductor of heat, but a good conductor of electricity. Mercury has a single electron configuration that strongly resists the removal of an electron, making it behave similarly to noble gas elements.
Is molten mercury a poor conductor?
Mercury is the only metallic element that is liquid at standard conditions and if we compare to most metals, it is a poor conductor of heat, but a fair conductor of electricity.
Is mercury best conductor of heat?
Why is mercury a good conductor of heat but not water?
Which liquid is a good conductor of heat and electricity?
Mercury is the liquid which is good conductor of heat.
Which liquid is the best conductor of electricity?
Water containing dissolved salts and minerals conducts electricity well, whereas pure water conducts electricity poorly.
What is the best liquid conductor of electricity?
Mercury (pictured) is the best liquid conductor of electricity. Why Is Mercury So Good At Conducting Electricity? Mercury is different to most metals, as it’s actually a liquid at room temperature. As a metal, mercury is full of charged ions (positive and negative particles), and this makes it a very good conductor of electricity.
Is Mercury a good conductor of electricity?
is mercury a good conductor is mercury a good conductor is mercury a good conductor yes, it is. it is a good conductor of both heat and electricity. Is polystyrene a good electrical conductor?
Why is water a good conductor of electricity?
Most liquids are good at conducting electricity – especially acidic ones (like the ones that you get in battery acid), or liquids with a lot of ions in them. Water is an okay conductor of electricity when it’s pure, but it becomes a better conductor when you add salt.
Why doesn’t Mercury melt at low temperatures?
Because this configuration strongly resists removal of an electron, mercury behaves similarly to noble gases, which form weak bonds and hence melt at low temperatures. On the periodic table, Mercury belongs to group 12 and period eight (8).
