A solvent pressure up to 1000 psi may be used. [Pg.98] Many solids show marked swelling as a result of the uptake of a gas or a liquid. Web3. Ideal and non-ideal porous solids. In an ideal porous solid, the solid phase is microscopically homogeneous and isotropic, and the pore space is fully connected. At the grain level, micro-homogeneity implies that the material is made of the same mineral and micro-isotropy suggests that the material deforms the same in all directions. china 1914 year fatman silver one dollar coin
