Hey guys, these pics should be self explanatory. But as we see why sublimation needs less energy than evaporation it is a scaffold with broken pillar. If we cancel one part of the scaffold in ice and its crystallic structures we generate the torn part. This part intrudes whole scaffold and the structure melts faster. In fact this process of going from firm ice towards a gas is called the sublimation. And what is evaporation? It is a change of liquids towards gasses. So ice is skipping one status and it is liquids, it immediately jumps from firm status towards gasses. That's it guys :)
