Explain why the exact time or duration of burning is needed?

The exact time or duration of burning is crucial for several reasons, primarily related to safety, efficiency, and quality control. Accurate timing ensures that materials are not over- or under-burned, which can lead to hazardous situations, such as uncontrolled fires or the release of harmful emissions. Additionally, precise duration helps optimize processes in industrial applications, affecting productivity and cost-effectiveness. In culinary practices, for instance, knowing the exact duration is essential for achieving the desired taste and texture of food.
