All solids expand as they are heated but I guess you want some examples where this is either useful or a problem: Useful * Bimetalic strips used in thermostats. They are made by joining 2 metals with different rates of expansion together, as they get warm they bend one way, as they get cold they bend the other. Problem * Long pipes have to have S bends in them to allow for the expansion/contraction otherwise they buckle or snap. * Railway lines are laid with gaps in them so that there is room for them to expand. (This is where the ta ta ta tap sound comes from as the wheels go over the gaps.) * Bridges have to have be suspended to allow for expansion.
Some non-examples of thermal expansion would include the boiling of water, which involves a phase change rather than expansion due to temperature increase, and the stretching of a rubber band, which is a different mechanism of deformation unrelated to temperature change. Additionally, the growth of a plant is not an example of thermal expansion.
Two examples of thermal expansion in solids are the expansion of a metal rod when heated, causing it to increase in length, and the expansion of a bridge beam on a hot day, resulting in the beam bending slightly due to the increase in temperature.
Chemical reactions and magnetic fields are not examples of thermal expansion. Thermal expansion specifically refers to the increase in size of a material when heated and the decrease in size when cooled.
Expansion may not be useful if it leads to unsustainable growth, stretching resources thin, causing quality to decline, or losing focus on core objectives. It can also be detrimental if not carefully planned and executed, resulting in increased costs without corresponding benefits. Additionally, expansion can create added complexities and challenges that may outweigh the potential advantages.

Expansion is useful because it is used for lots of thing such as blowing up tires, balloon's, and much more.TYLERNBIS
For example some useful isotopes: 241Am, 242mAm, 243Am.

There are several expansions for the acronym RFE. Some examples include request for expansion, resources for economics and radio frequency engineering.
There are many useful physical therapy exercises. Some examples of useful physical therapy exercises include stretching, flexibility techniques, and endurance testing.
