What is Adhesion and what is Cohesion?
Cohesion ia property of identical molecules to form agglomerates; a common example is the assembly of mercury from small bubbles into a larger one.Adhesion is the attraction between molecules of different chemical nature.
What is the leading cause of surface tension in most common liquids?
I believe all liquids have intermolecular forces of attraction between the molecules, whether they are small forces such as dispersion forces or stronger ones like hydrogen bonding in water etc. When in, "Bulk" such as in the middle of a liquid (not the surface) these forces are experienced all around the molecule in equal amounts and therefore no net force is experienced. However, at the surface of the liquid there are no attraction forces from above and so the molecules experience a net downwards pull. This causes the molecules at the surface to be pulled into the liquid, compressing the space at the surface. This smaller, denser and more packed surface is what causes the surface tension...correct me if I'm wrong. :)
What substance has the largest surface tension at room temperature?
Water has the highest surface tension of common liquids at room temperature. This is due to its strong hydrogen bonding, which creates cohesive forces between water molecules that pull them together and give water its high surface tension.
What are the common electroplating problems and their corresponding solutions?
Common electroplating problems include poor adhesion, blistering, pitting, and roughness. Solutions include proper surface preparation, adjusting plating parameters, and using appropriate additives to improve the quality of the plated surface.
The attraction between unlike substances is?
called adhesion. It refers to the molecular force of attraction between different substances that causes them to stick together. Adhesion is a common phenomenon in nature and plays a critical role in various processes such as capillary action and wetting.
What do cohesion surface tension and adhesion all have in common with reference to water?
Cohesion, surface tension, and adhesion are all properties of water that stem from its ability to form hydrogen bonds between water molecules. Cohesion refers to water molecules sticking to each other, surface tension is the result of the cohesive forces at the surface of water, and adhesion is the attraction of water molecules to other substances.
What do cohesion and surface tension have in common with reference to water?
Between water molecules a big cohesion force exist; this is the cause of the high surface tension of water.

What do cohesive surface tension and adhesion have in common with reference to water?
Cohesion: When things stick to each other (WATER) Adhesion: When things stick to other things (ALSO WATER) Surface Tension: a property of the surface of a liquid that causes it to behave as an elastic sheet. Think of it as the thing that helps insects to glide along the water. (ALSO WATER)
A consequence of the surface tension of water is what?
capillary action is a common consequence of surface tension.

How do you measure surface tension and what methods are commonly used for this measurement?
Surface tension is measured by determining the force required to break the surface of a liquid. Common methods for measuring surface tension include the drop weight method, the capillary rise method, and the maximum bubble pressure method.
What are some examples cohesion in real life?
Cohesion in real life can be observed in various contexts, such as the way water molecules stick together, forming droplets and enabling surface tension. In social settings, cohesion is evident in strong community bonds where individuals support one another, enhancing group solidarity. In teams, cohesion manifests as members work collaboratively towards common goals, fostering a sense of unity and shared purpose. Additionally, in literature, cohesive devices like repetition and transitional phrases create smooth flow and clarity in writing.
Which liquid has the lowest surface tension?
if you are doing a science project......you might wanna try diffrent liquids on the effect of (surface tension).... milk water juice paperclip water is best for the atraction of ST. milk and the juice is what reduces ST the best The body contains a natural surface tension reducing substance called surfactant.It is found in the lungs and prevents the lungs from collapsing due to surface tension when you exhale
