Mercury is the only metal that remains liquid at room temperature and it expands and contracts evenly over a large temperature range of -40to +300 degrees. Unfortunately it is toxic when the thermometer breaks and so alcohol is replacing Mercury for every day -10 to 100degree C thermometers as used in school labs. Electronic temperature sensors,like thermocouples, are taking over for higher temperatures.
What else can I help you with?
What liquids are used in thermometer?
Mercury and 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?
Actually anything that won't freeze or boil at the operating range of the thermometer. The most common are mercury and alcohol.
What metal is found in a thermometer?
The metal that was used in thermometers was mercury, however now alcohol is usually used.
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 in liquid in thermometer?
mostly Mercury but there are some with alcohol
What else can be used in a thermometer instead of mercury?
Alcohol, usually with a red dye in it
What type of thermometer is widely used in science classrooms?
Frequently thermometers filled with an alcohol; but also thermometers with mercury, with thermoresistance, thermocouples, etc.
Who invented the mercury and alcohol thermometers?
Daniel Gabriel Fahrenheit invented the mercury thermometer. Ferdinand II invented a thermometer using alcohol but it was very inaccurate.
What is the advantage and disadvantage of using alcohol in thermometer?
u don't have to flick the thermometer to reset the temperature reading when you use an alcohol based thermometer (unlike a mercury thermometer where you have to flick and flick and flick flick flick that thermometer for the mercury to be reset so that you can make an accurate reading) a disadvantage is that the alcohol thermometer is slightly less acurate The biggest advantage is that alcohol is not nearly as toxic as mercury, so that if the thermometer breaks, you won't be poisoned.
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 are fluids used in the thermometer?
Alcohol or mercury are commonly used as the fluids in thermometers. Mercury was commonly used in the past but is being phased out due to its toxicity. Alcohol is a safer alternative that is used in most modern thermometers.
