What is the characteristic explosion velocity of a low explosive?

• A. Greater than 1000 m/s
• B. Less than 500 m/s
• C. Less than 1000 m/s
• D. Exactly 1000 m/s

Answer: (C)

The characteristic explosion velocity of a low explosive is generally considered to be less than 1000 m/s. Low explosives, such as black powder and smokeless powder, deflagrate rather than detonate. This means they burn at a slower rate, leading to a lower explosion velocity compared to high explosives, which can exceed 1000 m/s. Low explosives typically have velocities ranging from around 70 to 900 m/s, which aligns with the limit set by the correct answer. Understanding this distinction is essential in the field of fire and explosion investigations, as it helps in identifying materials involved in explosive events and their potential hazards.
