Ceramic
To produce a strong ceramic piece, silicon carbide particles are
compacted and baked at high temperature. The specific gravity of
SiC is 3.2g / cm3. The ceramic piece is weighed
respectively when dry (200 g), after soaking in water (223 g) and
while suspended in water (211 g). Calculate the apparent porosity,
actual porosity, and volume fraction of pores that are closed.
