Answer

Brief Explanations:

  • When ice freezes, it is a process of losing heat. According to the kinetic theory, the kinetic energy of molecules is related to temperature. Lower temperature means lower kinetic energy, and since kinetic energy (E_{k}=\frac{1}{2}mv^{2}) (where (m) is the mass of the molecule and (v) is the speed), a decrease in kinetic energy (due to lower temperature during freezing) leads to a decrease in the speed of water molecules.
  • In gases, the intermolecular forces are the weakest compared to solids and liquids. So, gas particles are spread farthest apart and can move freely. In solids, particles are closely packed in a fixed - position lattice, and in liquids, particles are closer together than in gases and have more restricted movement compared to gases.

Answer:

  • First question: The water molecules decrease their speed.
  • Second question: gas
