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...

*Explanations should be brief. Draw a box around each final answer, if applicable.* 1. Consider intermolecular forces and kinetic energies with respect to a solid and a liquid. Explain why molecules in a liquid are free to move past each other, while molecules in a solid are held in fixed positions. 2. Use your knowledge of intermolecular forces to provide an explanation for why the boiling point of 2-hexanol is higher than the boiling point of 2,3-dimethyl-2-butanol. Be sure to...
