How does hydrogen bonds help the transport of water in plants?
Each water molecule pulls on other water molecules as water is transpired from the leaves of the plant. This allows free movement of water throughout the plant.
What is the difference between capillary action and surface tension?
surface tension is a product of cohesive forces (eg. water to water forces in a bubble) whereas capillary actionis a product of adhesive forces (eg. water climbing up a thin glass tube)
What is the cohesive forces between water molecules result in a tight elastic skin at the boundary between the liquid and the air?
surface tension
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.
Water beads up on wax paper because its cohesive forces are greater than the adhesive forces?
Yes, water beads up on wax paper because its cohesive forces are greater than the adhesive 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
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 are the two strongest forces of nature?
Fire & Water !
What is the attractive forces between like molecules?
Cohesive force is the attractive force between like molecules. Cohesive forces are also known as intermolecular forces and can also be repulsion forces.
What is sticky water?
Water is sticky and clumps together into drops because of its cohesive properties. On the molecular level, it is due to intermolecular forces.
Why does drop of water appear like pearl?
A drop of water appears like a pearl due to the cohesive forces among its molecules. Forces of attraction between water molecules and other molecules called adhesive forces.
Is water cohesive or adhesive?
Cohesive
How does hydrogen bonds help the transport of water in plants?
Each water molecule pulls on other water molecules as water is transpired from the leaves of the plant. This allows free movement of water throughout the plant.
Why does friction act more on object moving through water than the one moving through air?
Water has high cohesive forces
What is a good Sentence for Cohesive Forces?
The rigors of battle and the constant threat of death were the cohesive forces that bound the soldiers together. There is brotherhood in times of suffering.
