1. It remains in liquid state for a wide range of temperature with freezing point at -39 degree Celsius and boiling point at 357degree Celsius. It can therefore be used to measure a wide range of temperature.
2 It is an opaque and shiny liquid and is clearly visible in glass making it convenient to read the temperature.
3. It has a low specific heat and thus needs very small amount of heat from the body who's temperature is to be measured, to reach the same temperature of the body.
4. Mercury does not stick to the glass surface at certain points so the reading obtained by seeing the mercury level is almost accurate.
5. It has a uniform linear expansion and thus equal divisions represent equal intervals of temperature.

Why is alcohol preferred over mercury as a thermometric liquid?
Mercury is very toxic and can cause nerve damage and once it enters the body is just about impossible to get out. Alcohol is a much less hazardous substance. Even though it can be toxic, the body easily breaks it down in low doses. . Also, alcohol is commercially more abundant and less expensive than mercury.
What are thermal properties?
when objects are heated or cooled, their temperatures change, along with some of their properties, these properties are known as Thermometric Properties. Examples include: when objects are heated, they expand, when they are cooled, they shrink. Another is, if an object is heated, its' gaseos pressure will increase and will decrease when object is cooled.
What material is used for thermometer?
Mercury is used in thermometers. The mercury is the red substance in the thermometer that rises when you put it in your mouth.
Why was Mercury used for thermometers?
Mercury is a liquid at room temperature; this made it a useful substance in thermometers. As the mercury heated up, it expanded; this indicated the temperature of the surroundings. Similarly, the colder it got, the more the mercury 'shrunk' so it indicated the low temperature.
What liquid is inside thermometers?
If the liquid is silver, it is liquid mercury (Hg). If the liquid is red, it is coloured ethyl alcohol (C2H5OH).
What is the advantages of mercury as a thermometric substance?
list the advantages of mercury in thermometric substances
Why is mercury preferred to alcohol as a thermometric fluid?
what are the qualities of mercury over alchoholic as thermometric liquid
Why is the mercury used as a thermometric substance?
Its High boiling pointIts low melting pointIt does not stick any glass
What is the liquid in thermometer's called?
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
Why mercury is preferred as a thermometric substance?
Reason1.The mercury is good conductor of heat and expand rapidly and thus the temp;change quickly. 2.Mercury has a low heat capacity3.The mercury is opeque to light and can been seen clearly4.The mercury does not stick with the wall of container.5.Mercury has a freezing point of -39c and boiling point of 357
Why alcohol is preferred as a thermometric liquid substance?
It won't freeze at reasonable temperatures (it freezes at -173 degrees F) and it's relatively non-toxic. Mercury freezes at -37 degrees F and it is highly poisonous.
Why is alcohol preferred over mercury as a thermometric liquid?
Mercury is very toxic and can cause nerve damage and once it enters the body is just about impossible to get out. Alcohol is a much less hazardous substance. Even though it can be toxic, the body easily breaks it down in low doses. . Also, alcohol is commercially more abundant and less expensive than mercury.
What is the importance of thermometric liquids?
Thermometric liquid is the liquid found in the thermometer that help in the up and down movement of the temperature.
Is mercury substance or mixture?
Mercury is a pure substance, more specifically it is an element.
If the substance is warmer then the Mercury in the thermometer the Mercury will?
If Mercury (element) is heated then like every other substance it expands.
Is Mercury a substance or mixture?
Mercury is an element and therefore a pure substance.
Why is mercury a pure substance?
Mercury is an element and is therefore a pure substance. There are no other elements in it.
