When is it best to use the displacement method to determine the volume of a solid? select all that apply. when the solid has straight edges of a common shape when the solid dissolves in the liquid when the solid is insoluble in liquid when the solid has an irregular shape

The displacement method to determine the volume of a solid is bet to measure a solid when it is insoluble in liquid and has an irregular shape.

The method consists in filling a recipient with a known amount of water, lets say a measuring cup with one cup of water. Then, put the solid inside it, totally covered by the water; measure the new volume at the water line, subtract the starting volume from this new volume, and you will have the volume of the solid.

The answer is C. and D. when the solid is insoluble in liquid and when the solid has an irregular shape.

dude the first thing it says is that copied answers will get a zero. plus it would take anyone on an incredibly long time to answer. ive seen 2 people asking the exact same question and their questions got taken down. i have the assignment too, and im in the progress of doing it. i suggest going to a more private website, because this is the first place teachers look.
