Answer:
As the phase changes occur, the freedom of motion of the particles increases
Explanation:
As the phase changes occur from solid to gas, the freedom of motion of the particles increases
At the solid state (let's say ice), the molecules of the solid are tightly packed and they are unable to move freely. When heat is applied to the state of the solid, ice it melts and the molecules of the solid gains kinetic energy and therefore tends to shift away from their mean fixed position due to heat. This kinetic energy possesses by this molecules allow them to move freely (energy due to motion). When further heat is applied to the liquid (above the boiling point), the molecules of the water vapourizes(turns to gas) and this molecules gain more kinetic energy more than they do in liquid state and were able to move freely more than in liquid. This shows that the freedom of the particles (molecules) increase with change in state from solid to gas.
