True or False: All explosives are sensitive to heat, shock, or friction?

The statement that all explosives are sensitive to heat, shock, or friction is true. This sensitivity is a defining characteristic of explosives, as it relates to their ability to undergo a rapid chemical reaction that can result in an explosion.

Explosives are categorized into two main types: high explosives and low explosives. High explosives, such as dynamite and TNT, are typically more sensitive to stimuli like shock and heat, and they can detonate under these conditions. Low explosives, like gunpowder, are less sensitive and generally require confinement to explode effectively but can still be shocked or heated to the point of combustion.

Understanding the sensitivity of various explosives to heat, shock, and friction is crucial for safe handling, storage, and use, making the statement accurate across the board for all types of explosives.
