Sample A is a solid yellow cube with a total mass of \( 50.0 \mathrm{~g} \). The cube is put into a pressure chamber and the pressure raised by pumping in nitrogen gas At a pressure of 55. atm an orange liquid is observed seeping from the cube. Liquid continues to seep from the cube as fong as the pressure is applied. Sample B i5 100. g of a coarse grey powder with a faint unpleasant smell. 15. \( g \) of the powder is put into a funnel lined with a sheet of thick paper. Distilled water is poured slowly over the powder. Most of the powder disappears, but of a gritty black sand-like material is left on the surface of the paper. Pouring more water over the black material doesn't change how much of it there is.
