Final answer:
Dynamite is an explosive that contains nitroglycerin as its major component. It is stabilized by mixing it with diatomaceous earth to increase its stability. TNT, another explosive, is valued for its insensitivity to shock and friction and can be safely combined with other explosives.
Step-by-step explanation:
Dynamite is an example of an explosive that contains nitroglycerin as its major component. Nitroglycerin is a highly unstable material that explodes rapidly when ignited, releasing large amounts of gases and heat. By mixing nitroglycerin with diatomaceous earth, the stability is increased, making dynamite less likely to explode upon physical shock.
On the other hand, TNT is known for its insensitivity to shock and friction, making it a valuable explosive. It can be safely poured or combined with other explosives because it melts at a temperature below its detonation point. TNT is often triggered by a pressure wave from another explosive to initiate detonation.
