Question

What is the reason behind the high surface tension of water?


The density of the water molecule helps it to cohere to nearby water molecules, forming a skin over it.


The polarity of the water molecule helps it to cohere to nearby water molecules, forming a skin over it.


The weight of the water molecule helps it to cohere to nearby water molecules, forming a skin over it.

i think its the secound one

Answer 1

Water has such a high surface tension because of HYDROGEN BONDS! The molecules of the water bind together and are very difficult to separate because of the strong dipole-dipole connection that occurs. And water is most dense at 4 degrees Celsius!
