Sometimes, however, you will get a container with a known volume of liquid in it, e.g., a one-liter bottle of I need to kmow how many kiloliters are ion 52 liters. When you weigh an object, it returns a number in pounds or kilograms, which represent weight units. If you're seeing this message, it means we're having trouble loading external resources on our website. Both liquid and solid materials can have a variety of densities. xref
After trees are cut, logging companies often move these materials down a river to a sawmill where they can be shaped into building materials or other products. Rather, they are aqueous solutions of these substances in the form
Specific Volume What if the specific gravity of the object is the same as the specific gravity of the liquid? I think its the lower case greek letter, rho, to describe density. If a substance's relative density is less than one then it is less dense than water and similarly, if greater than 1 then it is denser than water. Specific volume is most often used in engineering and in thermodynamics calculations for physics and chemistry. Using the above example
