Properties of water and gasoline

The video shows the difference between a polar liquid like water and a nonpolar liquid like gasoline. I am investigating properties such as surface tension and solubility. The solubility and properties of water are explained in the Chemistry 7 book on Apple Books. The water molecule's intra-molecular bonds are covalent, and inter-molecular bonds between the molecules are hydrogen bonds, as described in the Chemistry 9 book on Apple Books by Kaj Schmidt.
