So when the two non polar molecules in solution do not interact with one another we see that we have many of these water molecules found around the non polar surface and this basically decreases and limits the freedom of movement of the water molecule. And this is not a favorable event. This is not a favorable reaction because the entropy basically decreases compared to when these two nonpolar molecules were not in our solution. Now, what will happen is because of the second law of thermodynamics because when given a chance to, we want to increase the amount of entropy of our system and our universe in general. We have the hydrophobic effect take place and these non polar molecules will tend to aggregate because by aggregating, by combining we decrease the amount of water molecules that are found around the surface because we decrease the surface to volume ratio. And so what that means is in this case we had 1234-5678, 910, 1112, 13, 14, 15, 16, 17, 18, 19, 20, 212-223-2425 water molecules that were trapped.
