Which term describes a chemical that causes a sudden release of pressure, gas, and heat when subjected to sudden shock, pressure or high temperature?

• A. Explosive
• B. Compressed Gas
• C. Oxidizer
• D. Reactive

Answer: (A)

An explosive is a chemical that undergoes a rapid energy release when subjected to sudden shock, pressure, or high temperature, producing a large amount of gas and heat in a very short time and creating a powerful pressure wave. This instantaneous release is what distinguishes explosives from other hazards. A compressed gas is simply gas kept under high pressure in a container and doesn’t inherently detonate when shocked. An oxidizer helps fuel burn by supplying oxygen but isn’t defined by an explosive energy release. A reactive substance can participate in chemical reactions, but not all reactive materials explode; the defining feature here is the rapid, explosive energy release.
