![]() ![]() And so the liquid water molecules are really highly dense test because they're so highly packed and these liquid water molecules they're constantly forming and breaking H bonds or hydrogen bonds are constantly breaking and reforming. And so what you'll notice is that if we zoom into the liquid water down below, notice that the water molecules are really highly packed into this little small area. And so over here we have an image that shows you both solid ice up here, the top floating on top of the liquid water that is down below. And so if we take a look at our image down below, notice that we're showing you an example of how density of liquid water compares to solid ice. And this is incredibly important for life because it means that water is going to freeze from the top to the bottom, and so when it freezes from top to bottom, it creates a layer of ice on the top, and that layer of ice on the top is capable of insulating the liquid water that is below the surface, and this is incredibly important to sustain life. And so this means that solid ice is going to float in liquid water. This is important because solid ice is actually going to have a much lower density than liquid water, and things that have a lower density in liquids are going to float. ![]() And the lattice structure is what allows the water molecules to expand. And this is because they form very stable hydrogen bonds and a lattice structure. And this is because solid water molecules actually expand. And they're constantly forming and breaking hydrogen bonds, whereas solid water molecules and the ice form are much less packed, and that means that they are less dense. And so liquid water molecules are really highly packed together, meaning that they have a high density. In this video, we're going to continue to talk about the properties of water, specifically its density and comparing the density of liquid water to solid ice. ![]()
