Answer:

hey ....

adhesion is always dissimilar ...cling

cohesion is similar ...

....no of proton in hydrogen ....

Answer 2

Explanation:

➡️1.the process of sticking or the ability to stick to something

➡️2.the ability to stay or fit together well

➡️3.tending to repel or fail to mix with water.

➡️4.having a tendency to mix with, dissolve in, or be wetted by water.

➡️5.The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms. When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule.

➡️6.In the covalent bond between oxygen and hydrogen, the oxygen atom attracts electrons a bit more strongly than the hydrogen atoms. The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
