Explosives Are Substances or Devices Capable of Producing a Volume

Multiple Choice

Explosives are substances or devices capable of producing a volume of rapidly expanding gases that exert a sudden pressure on their surroundings. Chemical explosives are the most commonly used, although there are mechanical and nuclear explosives. All mechanical explosives are devices in which a physical reaction is produced, such as that caused by overloading a container with compressed air. While nuclear explosives are by far the most powerful, all nuclear explosives have been restricted to military weapons.

B) No mechanical explosives are devices in which a physical reaction is produced, such as that caused by overloading a container with compressed air
C) Some nuclear explosives have not been restricted to military weapons
D) All mechanical explosives have been restricted to military weapons
E) Some devices in which a physical reaction is produced, such as that caused by overloading a container with compressed air, are mechanical explosives
