Expert Answer:

a) Gaining energy via endothermic and phase shift from solid to gas, the kinetic energy of the particles increases since molecules move more in gaseous form than in solid forms.
b) The forces of attraction decrease due to heating.
c) Particles go from a structured crystalline arrangement to gaseous random arrangement and hence, particles go from minimal movement to free movement in a gaseous state.
