Using water displacement method, if an initial volume starts at 100mL and goes up to a final volume of 200mL after object has been put in,

I'm guessing it is asking for the volume of the object if so the answer is 100Ml

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.

hope this : d
