This document discusses the three states of matter - solid, liquid, and gas - providing examples of each. It notes that in our world there are things made of each state, and that solids can melt into liquids, liquids can evaporate into gases, and gases can condense back into liquids or freeze into solids, using the specific example of water changing between solid ice, liquid water, and gas vapor.
