The Short Answer
Hydrogen and Oxygen are both positive, but oxygen is more positive. Therefore the oxygen atom in water holds onto the electrons most of the time. Because of this, the water molecule looks little bit like a magnet, with the oxygen side being more negative (as it holds onto more electrons) and the hydrogen side being more positive. Because it is slightly magnetic, water molecules will be more strongly attracted to each other, and so it takes more energy to keep them apart. More energy means it takes a higher temperature before they become a gas. This idea of hydrogen holding onto less electrons and becoming positive is called hydrogen bonding. Interestingly enough, this is also why ice is less dense than water – When water freezes, because the molecules are like little magnets, the water molecules want to arrange in a specific way, which takes up a large volume.
