Adhesive force is the attraction between molecules of different substances. It allows substances to stick together, such as water sticking to a glass surface. Adhesive force is important in processes like adhesion, where two different materials are held together.

What is responsible for the attraction between water molecules?
Water molecules are attracted to each other by 'cohesive force'. It is the force that holds a droplet of water together in a raindrop, or in a semi-spherical shape if dripped onto glass. Water is also affected by ' adhesive force' which causes the droplet on glass to adhere (stick ) to the glass as well. In a thin glass tube the adhesive force makes the water move upwards.
Why does water stick to hand?
Water sticks to your hand due to the forces of surface tension and adhesion. Surface tension allows water molecules to stick together and form a "skin" on the surface of your skin, while adhesion causes water molecules to stick to the molecules on your skin, creating a bond. This adhesion is stronger than the force of gravity pulling the water downward, so the water sticks to your hand.
What is an adhesive?
An adhesive is something which sticks to another substance.
What cause capillary action?
There are following forces- Adhesive force between solid-liquid interface Cohesive force of liquids (consider water-oil system in a glass tube) The adhesive force between water and tube is greater than that of oil and tube because water is wetting fluid here. The surface tension of water is larger than that of oil. This imbalance in forces across the water-oil interface cause the upward motion of interface
What is the definition of adhesions?
Adhesive means something that will stick or adhere.
How do you calculate adhesive strength?
Adhesive strength is typically calculated by measuring the force needed to pull apart an adhesive joint. This is done by applying a controlled force and measuring the stress at which the joint fails. Adhesive strength is influenced by factors such as the adhesive material, surface preparation, and testing conditions.
What are some forces that can act when in contact?
cohesive force and Adhesive force
What is example of adhesive force?
An example of adhesive force is when water sticks to a surface, such as glass. This occurs because the water molecules are attracted to the molecules on the surface, creating a force that keeps them attached.
What is the major force acting on all objects in the universe?
nuclear force,gravitational force,magnetic force and adhesive and cohesive force
What factors affect buoyant force?
cohesive and adhesive force
If water spreads out on a glass plate is this an example or cohesive or adhesive force?
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.

Which of the four fundamental forces makes paint cling to a wall adhesive sticky?
The force responsible for making paint cling to a wall or adhesive sticky is the electromagnetic force. This force is responsible for the interactions between charged particles, such as attraction between opposite charges and repulsion between like charges. When paint dries, the electromagnetic force helps create molecular bonds that allow it to adhere to surfaces.

Surface tension allows water molecules to stick together and form a "skin" on the surface of your skin, while adhesion causes water molecules to stick to the molecules on your skin, creating a bond. This adhesion is stronger than the force of gravity pulling the water downward, so the water sticks to your hand.
Is the concrete is adhesive or cohesive?
adhesive
What is the technical term for superglue adhesive?
The technical term for superglue adhesive is cyanoacrylate adhesive.
Why is the angle of contact of mercury obtuse?
Cohesive force between molecules of mercury is more than adhesive force between molecules of mercury and those of glass. This results in formation of a convex meniscus for surface of mercury. Actually, cohesive and adhesive forces are phenomenon due to surface tension of a liqud. The angle made by mercury from the glass surface is obtuse.
