Sketch of sublimation and condensation for superparticles. Blue represents ice and red vapour. Left panel: ice superparticle, representing a mass M in the form of 4 physical ice particles, each of mass m, sublimates and turns into a vapour superparticle of mass M. Right panel: vapour superparticle of mass M condenses onto an ice superparticle of mass M, representing the mass 4 m. The physical ice particles are after the event represented by two ice superparticles, each representing a total mass M, but now in the form of 2 physical ice particles each with mass 2 m. Both mass and the number of superparticles are conserved between t₀ and t₁. In the case of condensation, also the number of physical particles is conserved.
