Down
- 2. insensitive to heat, shock, and friction (TNT, Dynamite)
- 5. determines what type material was burning
- 6. indicates what temperature the fire was burning
- 7. speed of detonation; supersonic shock wave
- 9. combination of oxygen with other substances to make new substances
- 10. substances, like gasoline, alcohol that make the fire process faster
- 11. a fire started deliberately
- 15. Ultra-sensitive to heat, shock, or friction with normal temperatures will have it detonate violently
