What effect do cohesive and adhesive forces of water have on the way you do laundry?
it helps clean dust and provides the cleanes and pupliters in the cloth time warmere it is .
What forces act on structures?
The forces that act on structures are, push because gravity pushes down on it. It doesn't have a pull because it has a firm foundation to keep it steady and the wind it pushes it over
Why h and he can t be liquified by linde method of liquefication?
HYDROGEN & He cant be liuefied because their atomic Masses are small . second reason is that intramolecular forces are not present in helium and they cannot form covalentbond London forces are weak then inter molecular forces so less energy is required to overcome these forces and gas cannot be cooled.
Why are structures built the way they are?
Because of the relative strengths of the forces of nature.
What is structual stress?
1. Stress: when a structured weakens because of too many forces.
Does water bead up on wax paper because its cohesive forces are greater than its adhesive forces?
Yes.
Why does water drop spread on glass surface while mercury does not?
Water has stronger adhesive forces than adhesive forses. Mercury on the other hand has stronger cohesive forces than adhesive. cohesive forces hold molecules of the same substance together , vice-versa for adhesive forces
Capillary rise is due to the action of adhesion . is it right or wrong?
If the shape of the meniscus is concave up then the cohesive forces are weaker than the adhesive forces. If the shape of the menicus is concave down then the adhesive forces are weaker than the cohesive forces. So capillary rise is where adhesive forces are stronger.
What are some forces that can act when in contact?
cohesive force and Adhesive force
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
Why a drop of water adopts sperical shape?
Cohesive forces in given case are greater than adhesive forces. So water molecules form spherical shape. This behavior is more prominent in mercury.
2 How can you explain Cohesion and adhesion in term of water molecules?
Water has both cohesive and adhesive forces. They are similar.The cohesive of water describes how the molecules of water are attracted to one another. We observe the cohesive forces of water when we see a drop of water sitting on a surface. The water does not spread because the molecules are attracted to one another. Surface tension of water is due to its cohesive properties.The cohesive forces of water are due to hydrogen bonding between molecules.Adhesive properties of water are how the molecules are attracted to other substances. We observe the adhesive forces of water when we see the edge of water in a glass is attracted up on the sides of the glass. This is most apparent when the diameter of the glass vessel is less than a centimetre. It is called a meniscus. Trees use this adhesive property of water to help suck water up from the ground. If the diameter of the glass is small enough, as in a glass capillary, the water will rise up the tube by itself due to adhesive forces.
What cohesive and adhesive forces draw water from the roots to the different parts of the plants?
Surface tension; Capillary action; and Turgor Pressure.
What is The meniscus composed of?
Meniscus is not composed of anything its a physical properties due to surface tension of liquids. It is dependant on the: cohesive forces - binds similar molecules together. adhesive forces - bind a substance to a surface. Water for example in a glass tube the meniscus is U-shaped, we say, that the adhesive forces between the water and glass are greater, than the cohesive forces between water molecule, but for mercury, the meniscus is curved downward therefore we would say ..... One other thing in narrow tubes the rise of liquids is called capillary action.
What effect do cohesive and adhesive forces of water have on the way you do laundry?
it helps clean dust and provides the cleanes and pupliters in the cloth time warmere it is .
How do particles move in a glass of water?
I think you mean 'capillarity' which happens in very thin tubes because the adhesive forces between water and glass molecules is greater than the cohesive force between water molecules alone. In narrow tubes, this is enough to pull the liquid up the tube.
What do Cohesion and Adhesion have to do with Capillary action?
The liquid rises up due to the forces of adhesion between the capillary and liquid.. It rises till the extent when adhesive and cohesive forces and external forces balance each other...
