Cohesion is the tendency of molecules to be attracted to similar molecules. Adhesion is the tendency of molecules to be attracted to dissimilar molecules.
Water is both cohesive and adhesive, as is ethanol alcohol. The cohesiveness of water can be demonstrated by filling a cup with water and placing a wet clothe over the top of the cup, then flipping the cup upside down. The water will not entirely spill out of the cup.
Mercury is cohesive, but not adhesive, so two drops of mercury will absorb one another, but dipping a clothe in mercury will not absorb it.
The phenomenon of cohesion and adhesion can be understood by looking at the molecular structure and charge distribution of a molecule.

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.
Why do water and alcohol cling to a glass rod while mercury does not?

Why alcohol used instead of mercury in modern thermometers?
Alcohol is used in modern thermometers instead of mercury because it is less toxic and poses less of a health and environmental risk if the thermometer breaks. Additionally, alcohol has a lower freezing point than mercury, allowing it to measure lower temperatures accurately.
What fluids can be used to measure temperature?
Common fluids used to measure temperature include mercury, alcohol, and thermochromic liquids. Mercury is toxic and less commonly used now, while alcohol-based fluids are safer alternatives. Thermochromic liquids change color with temperature variations, making them visually helpful for temperature readings.
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 are the two most commonly found in liquid-in-glass thermometers?
The two most commonly found liquids in liquid-in-glass thermometers are mercury and alcohol. Mercury thermometers are used for high-temperature applications, while alcohol thermometers are used for lower temperatures due to their lower toxicity.
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.

Why is mercury not wet even though its liquid?
Mercury does not wet glass due to one of it's most significant properties. Mercury will not cling to the glass that contains it.
Why use of alcohol is preferred over mercury in thermometers?
Alcohol is less expensive and the compounds formed from oxides of Mercury are poisonous while alcohol is less problematic.
Are alcohol thermometers better than mercury thermometers?
Both alcohol and mercury thermometers are effective for measuring temperature, but alcohol thermometers are generally safer to use due to the toxicity of mercury. However, mercury thermometers provide more accurate readings at higher temperatures compared to alcohol thermometers.
What two substances are used in the thermometer's glass tube?
Most commonly, the two substances used in a thermometer's glass tube are mercury and alcohol. Mercury is traditionally used in older thermometers, while alcohol (typically colored red) is used in modern thermometers as a safer alternative.

Which are the odd state alcohol oil oxygen mercury?
oxygen because it is a gas while oil,alcohol and mercury is liquid.
Differences between mercury and alcohol thermometers?
Alcohol is used to measure at low temperatures because it has a lower freezing point than Mercury. Mercury has a higher boiling point than alcohol, mercury boils at around 400 Co and alcohol boils around 80 C0.
What are two liquids that have been used in thermometers?
Mercury and alcohol (typically ethanol or dyed alcohol) are two liquids that have been commonly used in thermometers. Mercury is often used in industrial thermometers due to its high thermal conductivity, while alcohol is used in household thermometers for safety reasons.
Which liquid will boil last water or mercury or alcohol?
Mercury will boil last, as it has a higher boiling point than water and alcohol. Mercury boils at around 674 degrees Fahrenheit, while water boils at 212 degrees Fahrenheit and alcohol at about 173 degrees Fahrenheit.
