When steel is heated to a high temperature of 1000°F, it undergoes thermal expansion. This means that the steel beam will expand in length, causing it to elongate. This expansion occurs because the heat causes the atoms in the steel to vibrate more rapidly, leading to an increase in the average distance between them. As a result, the steel beam expands and elongates by 5 inches in this case.

75. One of the greatest hazards in firefighting is the threat of _____.

Explanation

Firefighting is a dangerous profession, and one of the greatest hazards faced by firefighters is the threat of building collapse. When a building is on fire, the intense heat and flames can weaken the structure, causing it to become unstable and eventually collapse. This puts firefighters at risk of being trapped or injured by falling debris. Building collapse can also hinder rescue efforts and make it difficult to control the fire. Therefore, understanding and mitigating the risk of building collapse is crucial for the safety and effectiveness of firefighters.
