Final answer:

Solids and liquids differ in molecular structure and shape, and the process of a solid changing into a liquid requires energy to break intermolecular forces.


Explanation:

Differences Between Solid and Liquid States:

  • Structure: Solids have a fixed, ordered molecular structure with particles in a fixed position, while liquids have a more random arrangement with particles free to move around.
  • Volume and Shape: Solids have a definite shape and volume, whereas liquids have a definite volume but take the shape of their container.

Process of Solid to Liquid Transition:

When a solid at its melting point changes into a liquid at the same temperature, energy is added to break the intermolecular forces binding the solid together, allowing the particles to move freely in the liquid state.
