Hi Will You are partially correct. As per the diagram on slide 8 of lecture #4, on a weight basis (right hand side of the slide), if the soil is dry, there would be no water and since air has negligible mass, the dry weight of the soil = weight of the solids. On a volume basis the volume of the solids does not change, just the relative proportion of pores (voids) filled with water versus air.
