Question

thermal expansion is something that must be accounted for in which of these professions? electrical wiring tile work road and bridge construction

Explanation:

Thermal expansion is a phenomenon where materials expand when heated and contract when cooled. In electrical wiring, wires can expand and contract with temperature changes, which can affect connections and cause issues like loose connections or damaged insulation if not accounted for. In tile work, tiles can expand and if no allowance (like grout lines) is made for thermal expansion, tiles can crack. In road and bridge construction, materials like concrete expand and contract. If expansion joints are not included, roads can buckle and bridges can be damaged. All three professions need to consider thermal expansion.

Answer:

electrical wiring, tile work, road and bridge construction
