Why does water stick to hand?
water exerts two types of force cohesive and adhesive force.Cohesive force exist between water molecules and adhesive force exist between water and other objects.therefore when our hand is dipped in water the adhesive force overtakes the cohesive force and thus water sticks to hand.Its same as the capillarity principle
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 mercury falls in capillary tube?
because,the adhesive force of mercury in more compared to the cohesive force which acts on a capillary tube. that's why mercury falls in capillary tube
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 are some forces that can act when in contact?
cohesive force and Adhesive force

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.

What two factors affect the strength of friction between two surfaces?
Cohesive or Adhesive force between the two objects.
Is the concrete is adhesive or cohesive?
adhesive
What is the pot life of an adhesive?
"Pot life" is how long an adhesive can stay in a glue pot before it starts to set up, and it differs from adhesive to 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.
What is an adhesive plaster?
tape coated with adhesive
