Answer :
Final answer:
Steam boilers are protected with safety valves, which automatically release steam to prevent over-pressurization and potential explosions.
Explanation:
Steam boilers are equipped with safety valves to prevent over-pressurization and potential explosions. These valves are designed to automatically release steam if the pressure inside the boiler exceeds the design limit, thereby ensuring the safety of the boiler and its surroundings. This is akin to how a pressure cooker operates, releasing steam through a valve to prevent explosion, as mentioned in the reference.
