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 adhesive force?
Adhesive force is the attraction between molecules of different substances. It allows substances to stick together, such as water sticking to a glass surface. Adhesive force is important in processes like adhesion, where two different materials are held together.
What makes a water molecule stick to there container?
Water molecules are polar, meaning they have a positive and negative side, which allows them to form hydrogen bonds with other molecules, like the container. This attraction between the water molecules and the container is called adhesion, which causes the water to stick to the surface of the container. Additionally, the surface tension of water also plays a role in keeping water molecules in close contact with the container.
Do mlecules in solids stick together?
Yes, molecules in solids stick together due to intermolecular forces like van der Waals forces, hydrogen bonding, and dipole-dipole interactions. These forces attract molecules to each other and keep them in a fixed position, forming a solid structure.
Is it true that water molecules look like a chain of atoms?
No. A water molecule only consists of three atoms bonded together.
What property of water allows it to stick to a dry surface such as a wooden countertop?
Water's property of cohesion allows it to stick to a dry surface like a wooden countertop. Cohesion is the attraction between molecules of the same substance, in this case, water molecules. This attraction allows the water molecules to stick together and to the dry surface, forming a thin layer.
How does adhesion and cohesion affect each other?
Adhesion is where water molecules stick to other things, and cohesion is where the water molecules stick to each other. The combination of this makes it so that together, they can climb up things like roots of a tree to give the tree water.
When water acts like a sheet it is known as what?
That is known as surface tension. It is caused by the cohesive forces between water molecules, allowing them to stick together and form a "skin-like" layer on the surface.
How water's properties attribute to it's cohesive behavior?
Water's cohesive behavior is due to its polar nature, with oxygen being slightly negative and hydrogen slightly positive. This creates hydrogen bonds between water molecules, causing them to stick together. Additionally, water's high surface tension is a result of this cohesive force among its molecules.
Why does jello stick together?
Because Jell-O is composed of long, stick-like molecules. When you dissolve it in hot water, those molecules separate, but as the liquid cools, they begin to stick together like a giant heap of straws. The water flows slowly through these straws because of frictional effects. The result is a stiff material that is given its structure by the straw heap. If you leave the Jell-O long enough, the water will seep out and make puddles on the plate. Because Jell-O is composed of long, stick-like molecules.

Can you explain the oil and water experiment and how it demonstrates the concept of immiscibility between oil and water?
The oil and water experiment demonstrates immiscibility, which means that oil and water do not mix together. When oil and water are combined in a container and shaken, they separate into distinct layers. This happens because oil molecules are nonpolar, while water molecules are polar. Since like molecules tend to stick together, the nonpolar oil molecules cluster together and repel the polar water molecules, causing the two substances to remain separate.
Is water polar and forms hydrogen bonds that helps molecule stick together?
Yes. Water is a polar molecule and forms hydrogen bonds with itself that helps to stick water molecules together. It can also form hydrogen bond with other polar organic molecules (with less nymber of carbon atoms) like alcohols, carboxylic acids etc., and is hence responsible for the solubility of these compounds in water.
How does a penny hold water?
A penny can hold water due to two properties: surface tension and cohesion. Surface tension causes the water molecules to stick together and form a dome-like shape on the penny's surface, while cohesion allows the water molecules to stick to each other and the penny, preventing the water from spilling over.

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.
Why do water molecules tend to stick together?
Although a water molecule has an overall neutral charge (having the same number of electrons and protons), the electrons are asymmetrically distributed, which makes the molecule polar. This polarity makes them bond together weakly.
Can water adhere and cohere?
When two things that are alike stick together, they cohere. Water molecules in a cloud cohere to each other forming a droplet of water. More of these droplets cohere to each other forming larger droplets. When the cloud becomes saturated with water droplets it rains. When two (or more) different things stick together, they adhere. When you get caught in a downpour and your clothes gets really wet, the water makes your clothes adhere (stick) to your skin.
Why does water stick to windows?
Water tends to cling to things because of its chemical properties. The oxygen in water carries a slightly negative charge where as the hydrogen carries slightly positive charges. Because of this, the molecules of water tend to cling together better, creating a high surface tension. It is this surface tension that helps water bead together on objects like glass.
