Asked by Dave
Can you identify a metal if you know its density? Explain
Do you think that determining the volumes of metal samples by measuring their dimensions and calculating would be more r less accurate than determining volumes by water displacement? Explain. Would measuring the dimensions of a solid always be possible? Explain.
I would like to see your reasoning and I will critique it; however, think about how accurately you can measure a regular solid versus how accurately you can measure a volume. Measuring a solid, of course, is not always possible except when it has a regular shape. That is, the volume of an irregularly shaped object must be determined some way other than by measuring its dimensions.
