Question

Why does one object stick to another? Why are certain materials (adhesives) inherently sticky? (That is, such materials stick to any substance)? The purpose of this laboratory is to explore the answers to the above two questions. You will obtain data for this experiment through observation and/or recollection. Record at least 20 observations of one object sticking to another, noting cause and effect whereever possible: (1) Two pieces of paper do not stick to one another. After stapling, the two pieces stick to one another in the vicinity of the staple. e another Ater-sta (3) I along with most other people I know, stick to the surface of this planet. I've seen films of people in space who float freely, however. (4) Cold cheese (5) Wet paint (6) Briars/brambles/stickers really stick in my dogs' fur, but don't stick to the floorat all Report write-up: Title: My Theory of Adhesion Purpose: The goal is to explain the factors influencing the process by which substances stick to one another, and why some materials (adhesives) stick to most everything Data Ona single page, record your 10 most relevant observations (see above) Conclusion On a single page (backside of Title/Purpose/Data), write down the factors

Explanation / Answer

1)let's understand this by an example...water molecules (two atoms of hydrogen and one atom of oxygen joined together) naturally stick to one another,there always exists some forces that make them do this are called cohesive forces ,and the process involved is called cohesion. also we see that the water droplets also stick to the glass without any help or glue. Different forces are at work here known as adhesive forces and the sticking process is called adhesion. Now the cohesive forces must be bigger than the adhesive forces or the water wouldn't form droplets at all. Instead, it would just spread out in a very thin layer on the glass—much as oil does when you spread it on water. But the adhesive forces are still pretty strong.

2)materials and products may adhere and inherently sticky, because of the presence of moisture, or due to the build up of a static charge. Our equipment can be engineered and tailored to address the handling of sticky materials. For example,bucket conveyors can be outfitted with electrically conductive buckets to dissipate static charge build up, or equipped with a bucket knocker to effectively discharge sticky and gummy materials.

examples:-Potting soil; plastics; pastilles; wax flakes; crumb rubber; struvite etc...

hope this will help you

thanks :)
