A student records the dry mass of a porous stone. Water enters some of its pores during a displacement measurement. The student wants the density calculated using the entire external volume, including the pores. How does water entering the pores affect the result?
The displaced volume is too small, so the density is too low.
The displaced volume is too large, so the density is too high.
The displaced volume is too small, so the density is too high.
The displaced volume is too large, so the density is too low.
