What special abilities do water molecules have because they are polar?
Because water molecules are polar, they exhibit both cohesion adhesive. They are cohesive because they stick to other water molecules, and adhesive because they also stick to other surfaces.
Why are water molecules cohesive?
The slightly negative charge on the oxygen atom of one water molecule forms a weak electrostatic attraction between the slightly positive charge on a hydrogen atom of another water molecule. This is called a hydrogen bond. The hydrogen bonding between the water molecules is why water is highly cohesive.
What makes water adhesive?
cohesion-- Water molecules stick to each other. adhesion-- Water molecules stick to other molecules. Water is a polar molecule because of oxygen is more electronegative. Hydrogen bonds create surface tension and result it water's cohesive and adhesive properties. Hydrophobic = repel water Hydropholic = affinity for water. ...... hahaha XD
Why is water extremely cohesive?
Because of hydrogen bonding.
Why water tends to resist changes in temperature?
Water is highly cohesive. Its molecules tend to resist increases in their motion. When water is heated, some of the energy is used to disturb the hydrogen bonds between neighboring molecules.
How do water drops hold on to the penny?
Water molecules stick together because of the electrical charges in the water create a bond.
Is cohesion a property of water?
It is a physical property because no new substance is formed.
What special abilities do water molecules have because they are polar?
Because water molecules are polar, they exhibit both cohesion adhesive. They are cohesive because they stick to other water molecules, and adhesive because they also stick to other surfaces.
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.
Why is a raindrop in spherical shape?
because water molecules interact as magnets check for "cohesive attraction" on internet
Some insects can stand on the surface of water because water?
Some insects can stand on the surface of water because water is usually adhesive and cohesive. This is made possible by the molecules in the water.
What is the cohesive properties of the water?
This property due to the formation of hydrogen bonds between water molecules is the cause of the water molecules sticking.
What type of bond joins neighbooring water molecules?
Cohesive bond
Why does water have a meniscus?
Surface Tension. this is caused by a cohesive force between the polarized water molecules.
What is the definition of cohesion force?
Cohesive force is the force of attraction between molecules of the same kind or of the same substance. Eg. cohesive force of attraction exists between water molecules
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.
Can you give some sentences using the word cohesive?
Water molecules are both cohesive and adhesive: they can stick together or stick to other surfaces.
