Question

Describe the motion of particles in ice, liquid water, and water vapor. Apply the kinetic theory of matter to explain the difference.

Answer 1

answer:

According to kinetic theory of matter, molecules of solids have least kinetic energy, molecules of liquids have more kinetic energy than solids and molecules of gases have most kinetic energy. Motion of particles of a matter is directly proportional to the amount of kinetic energy possessed by it. So, liquids have more amount of molecular motion than solids and gases have most amount of molecular motion. Accordingly Ice (solid) have least amount of molecular motion, water (liquid) have more amount of molecular motion than solids and water vapour (gas) have the most amount of molecular motion.
