FIELD: physical- chemical study of solids. SUBSTANCE: procedure establishing density of solid body includes weighing of examined body placed on measurement dish. Weighing is carried out in working fluid in air bubble, first under normal pressure, then under reduced pressure. Later solid body is removed from dish, dish is filled with working fluid and weight of dish with working fluid is found. After this density of examined substance is computed. EFFECT: increased measurement accuracy. 1 dwg
