Final answer:
The low-energy state of condensed matter that is characterized by structural rigidity and resistance to changes of shape and volume is a solid.
Step-by-step explanation:
The low-energy state of condensed matter that is characterized by structural rigidity and resistance to changes of shape and volume is a solid.
In a solid, the particles are closely packed together and have strong intermolecular forces that hold them in fixed positions, resulting in a rigid structure.
Examples of solids include ice, iron, and diamond.
