1 | Mercury has a much greater density than water. | |
2 | Think of anything else with the density goes down when it freezes, and think about where we would be if that wasn't the case. | |
3 | The population density of that country is 685 per square mile. | |
4 | In the world described by it, the differences in population density between countries would be less extreme than they are today. | |
5 | You would get that by integrating the density. |
