Final answer:
The substance with strong intermolecular forces, a high melting point, and resistance to compression is a solid. Molecules can change positions in the liquid, gas, and plasma phases of matter, as these allow for more movement due to fewer or no bonds between molecules.
Step-by-step explanation:
The characteristics described in the question indicate that the substance in question is a solid. Solids have relatively strong intermolecular forces, high melting points, and are not easily compressed. They have specific shapes and definite volumes due to the close proximity and strong forces between the atoms or molecules. Solids resist shearing forces and maintain their shape even when force is applied because the atoms or molecules are held in place by a rigid lattice structure.
In Which Phases of Matter Are Molecules Capable of Changing Their Positions?
The correct answer is option c. Liquid, gas, and plasma are the phases of matter in which molecules are capable of changing their positions. In liquids, the molecules are close to one another but can slide over each other. Gases and plasmas have molecules that are not bonded to neighboring atoms and can move freely to fill their containers. Unlike solids, whose atoms or molecules are fixed in place, liquids and gases allow their particles to move relative to each other.
