Why the mercury is the most used element in many thermometers?
Mercury is commonly used in thermometers because it has a broad liquid temperature range (-39°C to 357°C), a high coefficient of expansion, and is a good conductor of heat. These qualities make it ideal for accurately measuring temperature changes.
Is Mercury a good conductor of current?
Mercury is a relatively good conductor of electricity (it used to be used in positioning switches to complete an electric circuit when the switch tipped so that enclosed mercury cam in contact with two terminals e.g. a switch on the lid of a freezer box which turned the light on when the lid was opened). Mercury is a relatively poor conductor of heat (compared to most other metals).
Is calcium a good conductor of electricity and heat?
Yes, calcium is a good conductor of heat and electricity. Most metals are good conductors of heat and electricity. Most nonmetals are not good conductors of heat and electricity.
Is copper a good conductor of heat and electricity?
yes copper is a good conductor of heat only becuase it comes in the conductor of heat
Is cesium a conductor of electricity and heat?
yes it is good conductor of elasticity because it is a metal.
Is mercury a good conductor of heat?
Yes, mercury is a good conductor of heat. It has high thermal conductivity, which means it can transfer heat efficiently and evenly. This property makes mercury useful in applications where heat needs to be transferred quickly, such as in thermometers.
What are the advantages of mercury as a thermometeric liquid?
As mercury has a low specific heat yet is a good conductor of heat it has been the choice for thermometers. The ease of reading is due to the fact that the mercury does not wet the walls of the glass.
Is mercury good conductor of heta?
No. Mercury is a poor conductor of heat.
Is mercury a best conductor of heat?
Yes, mercury is a good conductor of heat but it is not the best conductor. Metals like copper and silver are better conductors of heat than mercury.
What is a good conductor of heat in liquid?
mercury
Why is there mercury in thermometers?
Mercury is used in thermometers because it is a good conductor of heat and expands uniformly with temperature. This allows for accurate measurement of temperature changes. Mercury also has a wide range of liquid phase at normal temperature and pressure, making it suitable for various temperature ranges.
How well does mercury conduct heat?
Mercury is a good conductor of heat. Unfortunately, heat will produce vapor which is toxic.
What is best conductor of heat among liquids?
Liquid metals such as mercury and gallium are the best conductors of heat among liquids due to their high thermal conductivity. Mercury is often used in thermometers because of its excellent heat transfer properties.
Mercury a good conductor?
All metals are heat conductors; mercury is not a special case.
Is mercury a better conductor of heat than glass?
No, it is not. The best thermal conductor among the metals is silver, and it is the best electrical conductor as well. There is a general "rule" in the natural world that thermal and electrical conductivity are proportionate among metals; they "track" together. If a metal is a better thermal conductor than another metal, it will be a better electrical conductor as well. It should be noted that the best thermal conductor of all known materials is the allotrope of carbon we call diamond. Interestingly, diamond is an electrical insulator.
Mercury good conductor of heat?
All metals are heat conductors; mercury is not special (8,3 W/m.K).
Mercury is a good conductor of heat or not?
All metals are heat conductors; mercury is not special (8,3 W/m.K).
