What characterizes low-order damage?

Low-order damage is characterized by a slow pressure rise that results in less severe impacts compared to high-order damage. This type of damage typically occurs in situations where energy is released in a more controlled and gradual manner, often leading to less extensive destruction. In contrasts to high-order damage, which involves explosive reactions that cause significant devastation, low-order damage manifests through a more subdued explosion or burst, allowing for some structural integrity to remain.

The other options describe scenarios that either entail higher levels of intensity or immediate responses associated with high-order events, such as rapid explosions or large-scale immediate combustion. These higher-energy reactions tend to result in widespread destruction, which is distinctly different from the nature of low-order damage. Thus, the correct answer highlights the unique characteristic of low-order damage — a slow pressure rise associated with a lower level of devastation.
