Homework Help: How does porosity effect density measurement?

  1. Nov 2, 2004 #1
    In one of my classes, we were talking about density measurement and one of the questions that came up was "how does porosity effect density measurement?"

    I understand that air fills the gaps in the material that is being measured. So is the answer to the question: because air, for example, is filling the gaps you won't get a true density measurement for that material???

    Sorry if my post seems confusing :confused: but any help would be great! Thanks! :smile:

    True enough; but if the total volume of pores is insignificant relative to the volume of the object as a whole, it won't matter much.
