Adhesion occurs when liquid molecules are attracted to the surface of a solid like a container, causing the liquid to stick to the solid. Cohesion, on the other hand, is the attraction between the liquid molecules themselves, causing them to stick together. In the case of a meniscus, adhesion between the liquid and solid container causes the liquid to curve up or down, while cohesion helps keep the liquid molecules together to form a curved surface.

What is the influence of adhesion and cohesion in liquid?

Adhesion is the attraction between molecules of different substances, while cohesion is the attraction between molecules of the same substance. Adhesion allows liquids to stick to solid surfaces, while cohesion allows liquids to stick to themselves, forming droplets or menisci. These forces are important in determining properties like surface tension and wetting behavior of liquids.


Does The meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid?

Yes, the meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid. The meniscus forms due to the cohesion between water molecules and adhesion with the test tube, which is a result of intermolecular forces acting uniformly on all water molecules at the surface.


What word is used for the curved upper surface of a liquid in a tube?

It is called a MENISCUS caused by capillary action betweem the molecules of the liquid and the molecules of the container, and resulting from surface tension within the liquid. In addition: Adhesion: Making one material adhere to another.


Why does meniscus of water in glass curves upwards?

The meniscus of water in a glass curves upward due to surface tension. Water molecules are more attracted to the glass than to each other, causing them to climb up the sides of the glass. This creates a concave meniscus shape.


Why does a meniscus create a curved line in a cylinder?

There are two principles you need to understand here called adhesion and cohesion. Adhesion is how much a substance sticks to another substance; cohesion is how much a substance sticks to itself. Water's adhesive forces are stronger than its cohesive forces which cause it to stick to the walls of a container to create an downward meniscus.

How does adhesion and cohesion results to the formation of a meniscus?

Adhesion between water and the walls of the container causes the liquid to climb the walls, while cohesion between water molecules creates a curved surface at the top of the liquid. The combination of these forces results in the formation of a meniscus, which is concave for water in a glass container and convex for water in a narrow tube.


What is the curve along the top of a liquids surface?

Meniscus.


What is the curve at a liquid surface?

The meniscus, which is creaded by adhesion of the liquid particles to the surface of the container. Water meniscus domes upwards - the water has greater bonding to its own molecules; Mercury meniscus domes downwards.


What is Adhesion and what is Cohesion?

Cohesion ia property of identical molecules to form agglomerates; a common example is the assembly of mercury from small bubbles into a larger one.Adhesion is the attraction between molecules of different chemical nature.


Why is water or alcohol or acid have a lower meniscus while mercury have an upper meniscus?

Surface tension will attract the water solution to the molecules of the container thus lifting it up on the edges. Mercury, being much more dense has no such attraction because it is a liquid metal.Answer:It is due to what is called cohesion and adhesion. The water molecules are attracted to each other through cohesion, which is the attraction between similar particles (by polarity). Adhesion is attraction between unlike molecules. When water is placed in a glass container, the forces of adhesion overcome the forces of cohesion, and the water climbs up the glass. Conversely, the attraction between mercury atoms (cohesion) is stronger than its attraction to the glass (adhesion). Therefore, the atoms pull together and away from the glass.

What do cohesion surface tension and adhesion have in common?

Cohesion, surface tension, and adhesion are all properties related to the interaction of molecules in liquids. Cohesion is the attraction between molecules of the same substance, surface tension is the result of cohesive forces at the surface of a liquid, and adhesion is the attraction between molecules of different substances. These properties all involve the forces that hold molecules together in a liquid.

What is holding liquid in straw?

Liquid is held in a straw by a combination of cohesion, adhesion, and atmospheric pressure. Cohesion is the attraction between molecules of the liquid itself, while adhesion is the attraction between the liquid and the inner surface of the straw. The atmospheric pressure pushing down on the liquid also helps to keep it in the straw.


What is the difference between cohesion and adhesion in terms of their properties and effects on the behavior of liquids?

Cohesion refers to the attraction between molecules of the same substance, while adhesion refers to the attraction between molecules of different substances. Cohesion causes molecules within a liquid to stick together, creating surface tension and allowing the liquid to form droplets. Adhesion allows liquids to stick to other surfaces, such as when water sticks to the sides of a glass. Both cohesion and adhesion play a role in determining the behavior of liquids, such as how they flow and interact with other materials.
