Determine whether each statement describes the solid state, liquid state, or gaseous state. Answer Bank gas This state is characterized by the lowest density of the three states. solid liquid liquid This state is characterized by an indefinite shape and high density. solid Temperature changes significantly influence the volume of this state. gas Pressure changes influence the volume of this state more than the other two states. solid In this state, constituent particles are less free to move around than...
