By the term "condensed", this refers to the density of a state of matter. As a rule of thumb, solids are the most dense because their molecules are very close together. Next is liquids because they flow compared to solids. The least dense are gases. Therefore, a change from a more condensed state to a less condensed state is boiling (liquid to gas).
The initials will still be 4 feet above the ground.
Trees do not grow from the bottom up. At the branch tips there is meristem tissue, so called the apical meristem. Trees grow in height from these apical meristems, so trees grow from the top and the initials on the bottom of the tree will stay at the same height above the ground.
