Why does water have surface question?

I think you mean surface tension. Water has surface tension

because water is a polar molecule, meaning the opposite sides of

the molecule do not share electrons equally. This means that one

end of the water molecule has a positive charge and the other has a

negative one. The Law of Electromagnetic Force tells us that

opposite charges attract each other. So, at the surface, where

there is no water above it, the top layer of water molecules

allighn themselves and because of the attractive forces in the

charged particles, they "stick" together. This is surface

tension.
