What is the density of ice compared to water?
OK, first I’m going to have to assume you mean normal, everyday, water ice. Not fancy ice from water that’s been treated specially to remove impurities and the like. That’s critical, so start from there. The reason ANYTHING floats on water is that its density is less than that of water. A battleship weighing hundreds of thousands of tons floats because when you count all the open air in a battleship, it’s less dense than the water. Ice floats on water with roughly 10% of the ice above the water, so we can figure that the ice is roughly .9 times as dense as water (or that water is roughly 1.10 times as dense as ice). The reason for this is that water has dissolved oxygen in it. It’s a goofy concept, but it’s there. As long as the water molecules are in liquid form, they kinda float around and the oxygen molecules float around, too. But when you freeze water, all the water molecules line up to form a cubical matrix, and there’s no place for the oxygen molecules to float around. As they’r
