Transcribed Image Text:An electrical contact material is produced by first making a porous tungsten compact that weighs
135 g. Liquid silver is introduced into the compact: careful measurement indicates that 105 g of silver
is infiltrated. The final density of the composite is 13.7 g/cm³. Calculate the volume fraction of the
original compact that is interconnected porosity and the volume fraction that is closed porosity (no
silver infiltration). The densities of tungsten and silver are pw = 19.254 g/cm and Pag = 10.49
