Is it true that some solids dissolve in water and other solids do not?
it's all about the structure of the particles and the bonds if the chemical bond are mostly ionic they will dissolve to form freely moving ions and some structures of atoms are much stronger like metallic bonds. covalent bonds do not dissolve easily but some covalent bonds break and dissolve in water. It's all about the bond and structures of different elements.
What happens when a polythene strip is rubbed on a woolen cloth and then placed near a thin stream of running water from a tap?

The polymer "polythene".
Does polythene dissolve?

What are the effects of polythene pollution?
One of the effects of the polythene pollution is that it interacts with water to form hazardous chemicals. It leads to the death of animals which consume the polythene which has not been disposed properly.
What are the Elements produced by polythene burning?
When polythene burns, it produces carbon dioxide, water vapor, and trace amounts of carbon monoxide and volatile organic compounds. Burning polythene releases harmful chemicals into the environment and should be avoided.
