Mercury is an element, a metal. Alcohol is the name of a familty of organic compounds made up of carbon, oxygen, and hydrogen atoms in various combinations. The only obvious similarity of the two substances is that some alcohols (ethyl alcohol, or ethanol, C2H5OH, for example ) share a common freezing point with mercury of about minus 40 degrees (Celsius or Fahrenheit), making them suitable for use in outdoor thermometers.
What else can I help you with?
Why alcohol used in laboratory thermometers instead of mercury?
Alcohol-based thermometers are used in labs because alcohol has a lower freezing point than mercury, making them suitable for lower temperature measurements. Additionally, alcohol is less toxic than mercury, reducing potential health and safety risks in laboratory settings.
How does a mercury pressure device work?
A mercury pressure device, such as a manometer, works based on the principle that the pressure of a fluid is directly proportional to the height of the fluid column. In a mercury manometer, a column of mercury is used to measure the pressure difference between two points. The difference in height of the mercury column indicates the pressure difference between the two points.
Would you rather use alcohol or Mercury in a thermometer?
Alcohol is a safer choice for a thermometer liquid as it is not as toxic as mercury, making it safer for both human health and the environment. Mercury can be harmful if it leaks or is accidentally ingested, whereas alcohol is less harmful if exposed.
Can mercury and alcohol mixed to become a thermometer?
Mercury and alcohol are not the thermometers but the liquids found in the thermometer they have different properties that make them uniqe for example alcohol is safe while mercury is poisonous,alcohol does not expand uniformly but has great expansion while mercury expands uniformly and has low expansion,alcohol is cheap while mercury is expensive,alcohol wets the glass while mercury does not.so alcohol can not combine to form a thermometer simply because they are the liquids found in it and not the thermometer itself.
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.
Give four difference between mercury and alcohol?
Different boiling points 2 Different melting points Mercury is a liquid metal , and alcohol(ethanol) is an organic compound. Mercury is poisonous and alcohol (ethanol) is not poisonous to human beings.
Does a Kelvin thermometer contain mercury or alcohol?
There is no mechanical difference between a kelvin thermometer and any other kind so I think it would be the same as other thermometers i.e. Alcohol (because it is not as dangerous as mercury)
Is there a difference between isopropyl alcohol and rubbing alcohol?
Yes, there is a difference between isopropyl alcohol and rubbing alcohol. Isopropyl alcohol is a type of alcohol that is commonly used as a disinfectant and solvent, while rubbing alcohol is a type of alcohol that is typically a mixture of isopropyl alcohol and water.

What is the difference between ethyl alcohol and ethanol?
There is no difference between ethyl alcohol and ethanol, they are the same substance. Ethanol is the chemical name for the alcohol commonly found in beverages and used in industry.
Is mercury denser than alcohol?
Yes, mercury is denser than alcohol. The density of mercury is about 13.6 times greater than the density of alcohol.
What is the size difference between Mercury and Earth?
