Why does water have more surface tension than methylated spirits?
For the same reason that it has a higher boiling point: There is more intermolecular attraction with water. This has something to do with its polarity and "hydrogen bonding"
Explanation of why the surface tension of water is greater than that of methylated spirit???
Water has more surface tension than methylated spirits due to waters strong intermolecular forces.
Plz name the intermolecular forces of ethanol,iodin and watee
Water has more surface tension than methylated spirits because of the difference in molecular structure and intermolecular forces.
To understand why water has higher surface tension, we need to consider the hydrogen bonding between water molecules. Water molecules are composed of two hydrogen atoms and one oxygen atom, and these molecules can form hydrogen bonds with neighboring water molecules. These hydrogen bonds create an attraction between the molecules, resulting in a cohesive force that holds the water molecules together.
On the other hand, methylated spirits, also known as denatured alcohol, is primarily composed of ethanol (ethyl alcohol) but also contains other additives. Ethanol molecules do not have the same strong hydrogen bonding capability as water. While ethanol can form some hydrogen bonds, the strength of these bonds is weaker compared to the hydrogen bonds in water.
The difference in intermolecular forces between water and methylated spirits contributes to the variation in surface tension. Surface tension is a measurement of the cohesive forces between the molecules on the surface of a liquid. The stronger the intermolecular forces, the higher the surface tension.
In the case of water, the hydrogen bonding between water molecules creates a strong cohesive force, making it possible for water to form droplets and maintain a relatively high surface tension. This cohesive force also explains why water has a concave meniscus when placed in a narrow tube.
On the other hand, methylated spirits, with weaker intermolecular forces, has lower surface tension. The weaker cohesive forces between the ethanol molecules result in a reduced ability to create a strong surface tension. As a result, methylated spirits tend to spread out more easily, forming a flatter meniscus in tubes.
To summarize, water has higher surface tension than methylated spirits due to its stronger intermolecular forces, particularly hydrogen bonding. These stronger cohesive forces allow water molecules to cling together more tightly at the surface, resulting in properties such as droplet formation and a concave meniscus.
