Adhesion and cohesion are physical properties of water that are caused by water's polarity. This, in turn, is caused by the shape of the water molecule, which forms a partial difference in charge across the length of that molecule, causing intermolecular attractions between water molecules. It also explains surface tension, the fact that water expands when it freezes, and 6-sided snowflakes.

Which of the following terms describes water molecules sticking to other water molecules?

The term that describes water molecules sticking to other water molecules is cohesion. This cohesive property is a result of hydrogen bonding between the water molecules.


Is the interaction between wax paper and water cohesive or adhesive?

The interaction between wax paper and water is adhesive. Adhesive forces are when two different substances stick together, whereas cohesive forces are when the same substance sticks together. In this case, the water molecules are attracted to the wax paper, causing them to adhere to each other.


The cohesive forces between molecules of mercury are much stronger than those between molecules of water Which substance has the greatest surface tension?

Mercury has the greatest surface tension due to the stronger cohesive forces between its molecules compared to water. Surface tension is the property of liquids that arises from the cohesive forces between molecules at the surface, causing them to minimize surface area.


What is about water molecules that helps explain why the water drops were difficult to split apart but easy to join together?

Water molecules have strong cohesive forces due to hydrogen bonding, which makes it difficult to separate the water drops. When the drops join together, these cohesive forces pull the molecules back together easily due to surface tension, helping the drops recombine effortlessly.


Is Methanol a more cohesive liquid than water?

Yes, methanol is generally considered to be a more cohesive liquid than water. This is because methanol has a lower surface tension and higher vapor pressure compared to water, leading to stronger intermolecular forces that promote cohesion.

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.


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.


Does water bead up on wax paper because its cohesive forces are greater than its adhesive forces?

Yes.

What forces are at work on water?

The primary forces at work on water include gravity, surface tension, and cohesive forces between water molecules. Gravity pulls water downward, while surface tension causes water molecules at the surface to bond tightly together, forming a barrier. Cohesive forces allow water molecules to stick to each other, contributing to properties such as capillary action and water's ability to form droplets.


Why is water rise in capillary tube wheras mercury falls in capillary tube?

This happens due to the difference in adhesive and cohesive forces. Water molecules are more attracted to the walls of the tube (adhesive forces) than to each other (cohesive forces), causing water to rise. Mercury has stronger cohesive forces compared to adhesive forces, so mercury is more attracted to itself than to the walls of the tube, causing it to be depressed or fall in the capillary tube.


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.


What is the Skin on a film of water called?

The skin on a film of water is called surface tension. It is caused by the cohesive forces between water molecules.


Why does friction act more on object moving through water than the one moving through air?

Water has high cohesive forces


Are cohesive forces greater than adhesive forces?

It depends on the material. In some materials, cohesive forces (forces between molecules of the same substance) are stronger than adhesive forces (forces between molecules of different substances), while in others, the opposite is true. Generally, cohesive forces tend to be stronger in materials with similar molecules, such as water.


What forces create the meniscus you see at the top of a liquid when you measure it?

The meniscus is created by adhesive forces between the glass and the water. THis means that the water water molecules are attracted to the glass so they can creep up the glass to a small degree. The water molecules are also attracted to each other through hydrogen bonding. These are called cohesive forces and they allows the water that creeps up the glass to bring other water molecules with them. The cohesive forces and adhesive forces can only resist gravity to a certain degree so in the middle the liquid curves downward.
