Another whole industry is based on information from density. All the ships in the world were created to evade the problem of sinking in water due to the fact that they were too dense. Mass also is very important in real life. It is the most reliable way to measure objects because it has no variables. Besides that, volume is important in figuring out how much storage space a person has and the space a room has for furniture.
Density is also important in the industry that keeps the world moving, petroleum.
Density can be used to determine if certain rock contains high quality petroleum and it can also be used to find pure petroleum in its most effective state. I, as well as everyone else, always try to make as accurate experiments as possible. But sometimes there are sources of error that we cannot control. These sources of error can not be totally stopped, but with some creativity these sources can be minimized. In my procedure there were a few sources of error.
