Density purpose to understand the compactness of planetary matter by density is defined as the average mass per unit volume it is a measure of how much. We can figure out if a bowling ball (or any object) will sink or float in water, if we know its density density is a measure of how much mass is present in a given. In this experiment you will compare various methods for the determination of the density of a liquid (coke and diet coke) density is a physical property, and.
Does it sink or float and why do some liquids mix together easily (think lemon juice and water for some tasty lemonade), when others don't mix together at all.
