They are things like firecrackers , bullets and dynamite.
Gunpowder and fireworks are low explosives. A low explosive has a shock wave that travels slower than the speed of sound.

Primary and secondary explosives. The definitions of these are rather loose, however typically primary explosives will detonate when ignited (example: mercury fulkminate), and secondary explosives require a shockewave to detonate (example: TNT). The most accurate definition is when used in the context of an "explosive train" whereby a fuse ignites the primary high explosive which undergoes deflagration to detonation transition, this detonation produces a shockwave which is used to initiate a secondary high explosive. So explosive compounds are classified into primary or secondary based there primary use.
Examples: low thermal and electrical conductivity, low hardness, they are brittle, low melting and boiling points, some are liquids or gases, low density etc.
liquids that have low viscosity seem to flow quickerexample: vinegar and water
bad conducter of heat bad conducter of electricity not reflective not bendable not mallable enough for you?
Have worked with explosives for 40 years, have not heard that term. There are high and low explosives and blasting agents.
high explosives, low explosives, explosive mixture and explosive compounds.
Low explosives (black powder) High explosives (nitroglycerine) Blasting Agents (ammonium nitrate/ fuel oil)
I have low tolerance for ignoramus people.
they leave large ordnance fragments containing explosives and may leave chunks or pieces of exposed explosives; do not remove remaining debris.

some of the low cost fuels are bio ethanol,bio methanol,cellulose bio mass etc.
Many explosives are not detectable by x-ray machines, due to their low density. Inspection or bomb sniffing dogs are the only reasonably reliable ways to detect such low density high explosives.
can low level living exist simultaneously with high levels of per capital income? and give examples
Chemical explosives may be low or high explosives. Low explosives, such as black gunpowder, actually burn- but at a very high speed. That burning produces a rapidly expanding gas. The gas exerts a push on things around it, and can propel bullets, break rock, etc. High explosives are unstable chemicals, usually in the nitrate or chlorate families. When enough energy is put into them, they react by dropping to a lower energy state. In doing that, they rapidly give up the stored chemical energy in the form of heat, formation of gasses, and blast. The exact chemical reaction varies from one explosive to another.
