Explanation;

  • Matter is anything that has weight and occupies space. It occurs in three states namely, gases, liquids and solids.
  • All matter is made up of tiny particles that are in constant motion.
  • According to kinetic theory of matter, matter is made of many particles, that is atoms or molecules, that are in constant motion.
  • In gases, the motion of particles are in constant random motion, they move freely. In liquids, the motion is constrained by the liquid's volume, while in solids the motion of particles is greatly constrained to a small space.
