Which outcome occurs when early steam engine boilers lacked safety valve precision during the Industrial Revolution?

💡 Explanation

When early boilers lacked precise safety valves, pressure buildup occurred because manual control was inconsistent, leading to catastrophic explosions when exceeding material limits. Therefore, systematic boiler explosions resulted, rather than corrosion, reduced efficiency, or friction, which require different operational failure modes.
