If water spreads out on a glass plate is this an example or cohesive or adhesive force?
Bengalgela08
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.

What makes water wet?
Water is a wetting liquid but Mercury is non wetting so not the all liquid are wetting it depends upon Adhesive and cohesive forces , the liquids having strong adhesive force than cohesive become absorbed on a solid surface and that surface becomes wet but the liquids having strong cohesive force can not absorbed on a solid surface so material remains dry and such liquids are non wetting liquids as Mercury, so water is wetting liquid due to its strong adhesive force.
Why is water water?
Because water is a liquid and one of the main properties of liquids are that they are wet, water is also wet.Another reason is also because water is a compound meaning that the stuff that creates it (hydrogen and oxygen) lose their properties when thy are mixed together.Answer"Wet" is just a describing word that we use to describe something that has a liquid on or in it. So why does water act this way? Simply because it is a liquid and acts as suchWater is a wetting liquid but Mercury is non wetting so not the all liquid are wetting it depends upon Adhesive and cohesive forces , the liquids having strong adhesive force than cohesive become absorbed on a solid surface and that surface becomes wet but the liquids having strong cohesive force can not absorbed on a solid surface so material remains dry and such liquids are non wetting liquids as Mercury, so water is wetting liquid due to its strong adhesive force.
What is it called to move upward through narrow tubes against the force of gravity?
If your referring to liquids going up the narrow tubes, than it can be called "Capillary action" or "capillarity". It occurs when the adhesive intermolecular forces between the liquid and a solid are stronger than the cohesive intermolecular forces withing the liquid. Otherwise, it would be "lift" and that just takes us to physics...
What is an example of a contact force?
Friction.
An example of a contact force is?
the force between two masses A and B which are lying next to each other and a force F is being applied on one of the masses, for example A.
What are some forces that can act when in contact?
cohesive force and Adhesive force
What factors affect buoyant force?
cohesive and adhesive force
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 the major force acting on all objects in the universe?
nuclear force,gravitational force,magnetic force and adhesive and cohesive force
What two factors affect the strength of friction between two surfaces?
Cohesive or Adhesive force between the two objects.
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.
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 makes water wet?

What force enables the stem to absorb water?
Adhesion and Cohesion or cohesive attraction or cohesive force
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.
What happens when a liquid makes an angle of 90 degree with inner wall of the capillary?
when adhesive force becomes equal to cohesive force then the contact angle becomes 90 degree. At such a peculiar situation the meniscus remains parallel to horizontal line.
Are cohesive forces greater than adhesive forces?
yes, as the molecular force is attractive at larger distance apart in case of similar molecules rather than dissimilar molecules. Kamal panda_kamal@rediff.com
