Why is mercury a more suitable liquid for thermometer than water and alcohol?
Wiki User

Non sticky to the glass surface
Because of shining its level can be easily seen
Boiling point is high
Being metal, coefficient of expansion is high
Above all, its angle of contact with glass is obtuse and so its meniscus is convex.

Mercury has a wider temperature range, remains in liquid form over a wide range of temperatures, has a high coefficient of expansion, and is visible in the capillary tube. Water and alcohol have more limited temperature ranges and may freeze or evaporate at typical temperature ranges used in thermometers.

∙ 13y agoMercury is opaque making it clearly visible in the capillary tube of a thermometer.But alcohol only after adding a dye (generally red) is clearly visible through glass.Mercury does not stick to the side of the glass capillary tube of a thermometer, allowing accurate temperature measurement, but alcohol wets
glass.Mercury has a high boiling point of about 357oC and can be used to measure high temperatures unlike alcohol which has a low boiling point of about 78oC.So mercury is used instead of alcohol in most theremometres.

∙ 12y agoBecause mercury has a higher boiling point, and lower freezing point than alcohol. Methanol alcohol boils at around 64 C - making it useless to measure high temperatures. Mercury Freezes at minus 38 C, and boils at 357 C.

What is liquid-in-glass thermometer?
what do they use for the liquid in glass ball thermometer
The liquid most commonly used in a thermometer is either mercury or?
alcohol, such as ethanol or dyed ethyl alcohol. Mercury and alcohol are both used in thermometers due to their ability to expand and contract with temperature changes, allowing accurate measurement of thermal fluctuations. Mercury is less common now due to its toxicity.
What is the liquid in the themometer?
The liquid in a thermometer is typically mercury or alcohol. Mercury is commonly used in traditional thermometers, while newer digital thermometers may use alcohol. These liquids expand and contract with temperature changes, allowing the thermometer to measure the temperature accurately.
What liquid is inside thermometers?
Most traditional thermometers contain mercury as the liquid inside. However, modern thermometers use alcohol or a similar non-toxic liquid.
What does the volume of a thermometer refer to?
The volume of a thermometer typically refers to the amount of liquid (such as mercury or alcohol) contained within the thermometer's bulb and capillary tube. This liquid expands or contracts with changes in temperature, allowing the thermometer to display the temperature reading.
What is in liquid in thermometer?
mostly Mercury but there are some with alcohol
What is liquid-in-glass thermometer?
what do they use for the liquid in glass ball thermometer
What type of liquid do you use in a thermometer?
Mercury and alcohol [liquid elements]
What is the liquid in a thermometer?
The liquid in a thermometer is usually mercury or colored alcohol. These substances expand or contract based on temperature, allowing the thermometer to measure changes in temperature.
What is the name of the liquid in a thermometer?
The red liquid in a liquid-in-glass thermometer is mineral spirits or ethanol alcohol mixed with red dye. A grey or silver liquid inside the thermometer is mercury. Mercury thermometers are not used anymore due to the dangers associated with mercury.
What liquid is found in a clinical thermometer?
The liquid in a clinical thermometer is often mercury. But there are thermometers that use a coloured alcohol.
What are the two substances used in a liquid column thermometer?
The two substances used in a liquid column thermometer are mercury and alcohol. Mercury thermometers use mercury as the liquid inside the glass tube, while alcohol thermometers use colored alcohol such as ethanol or dyed ethanol.
Is it a solid liquid or gas found in a thermometer?
A liquid, typically mercury or alcohol, is found in a thermometer.
What happen to the liquid in a thermometer when it gets warm?
The liquid expand from heat. We use these expansion to indicate temperature. Common thermometer liquid is Mercury and alcohol.

What is the liquid in thermometer's called?
Mercury the liquid inside thermometer is mercury.. but it is called thermometric liquid.
