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.
Does water have strong cohesive properties?
In terms of causing different molecules to stick together (like glue holding pieces of paper together), water is relatively weak. However, in terms of water molecules holding tight to other water molecules, they are very strong because they have particularly powerful intermolecular forces (called hydrogen bonds) that keep the molecules together.
What is the biological exception to water being the universal solvent?
Many polar substances can dissolve in water. Lipids cannot dissolve in water because lipids are nonpolar, so there is no attraction between them. Water can stick to itself and other things. Water also expands when it freezes.
How does the hydrogen bonding between water molecules affect the properties of water?
It enables water molecules to stick to each other and to many other things.
Can leaves have hairy or waxy surfaces?
Yes. Many leaves have waxy surfaces to minimise water-loss through evaporation. Hairs on leaves inhibit insects and other animals from eating them.
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.
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 does water stick to itself?
Because of hydrogen bonds which help water molecules stick to each other. hope it helped i just learned it today
What adaptations do limpets have?
Major adaptations of the lobster include to large claws to defend itself and an exoskeleton which does same.
Why is metal anodizing important?
Metal anodizing helps reduce corrosion and water damage. Metal anodizing also helps paint and other coatings stick to metal surfaces better.
Which factor do you think has something to do with the differences in the number of water drops a coin can hold?
There are two factors that we see in water, it's adhesive and cohesive abilities. Better put, it's the ability for water to stick to surfaces as well as stick to itself. This gives an overall "surface tension" that will develop as the bead of water grows. This amount of mass and volume will get too great, however, and the water will no longer be able to hold itself together. If you wanted to lower the surface tension, adding soap would make it so that the water would break after fewer drops.
What property describes water sticking to other surfaces?
Adsorption.

Why is water both adhesive and cohesive?
Cohesion in water is the water being 'sticky' or attracted to itself. Adhesion in water is when the water is 'sticky' or attacted to other surfaces. Water is cohesive and adhesive because of it's properties. The oxyogen and hydrogen molecules are bonded together and are polar. Beacuse the molecules are polar the particales are therefore attracted to each other from negative to positive end (cohesion), but are also atracted to other particles in other surfaces, again positive to negative poles (adhesion). It's very important that water be both cohesive and adhesive for being good for solutions and other functions.
Why does water stick to copper pennies?
Water has two important qualities: cohesion and adhesion. Cohesion means that water "sticks" to itself, forming drops on a flat surface. Adhesion means that water sticks to other things, such as copper pennies. The water adheres to the coin and coheres to itself, forming a bulbous drop of water on the coin.
How will moisture form on a glass?
Cohesion and Adhesion. Adhesion is the property of water that makes it stick to other substances. For example, water on glass. Cohesion is the property of water that makes water stick to itself. For example, water droplets. Now you breath and the air has trace amounts of moisture, so when you breathe out, the moisture go from your mouth to the glass, and due to adhesion, it stays there for a while.
