What causes a red smoke?
Smoke particles are much larger than gas molecules, and instead better scatter the long wavelengths of red light. This is known as Mie scattering. When particle concentrations get really high, Mie scattering can dominate over Rayleigh scattering meaning we see the daytime sky as red rather than blue.
What does red smoke mean in war?

What’s the difference between fire with white smoke and fire with black smoke? Black smoke is full of unburned carbon particles, so not enough oxygen or too low a temperature for efficient burning. White smoke is where the carbon has been consumed and converted to CO2 and non-combustible residues only colour the smoke.
Is smoke coming out of exhaust normal?
Many times, this thick smoke is due to the likes of a blown head gasket, damaged cylinder, or a cracked engine block, which is causing coolant to burn. Thick white exhaust smoke usually indicates a coolant leak, which could cause overheating and put your engine at a serious risk of damage.
Will bad injectors cause black smoke?

What makes red smoke?
Composition. The primary dye component of old red-smoke formulation is 1-methylaminoanthraquinone (MAA) (40% of the total components) (Rubin and Buchanan 1983). MAA is also called disperse red 9.
What chemicals causes red smoke?
doi: 10.17226/5582. The obscurant portion of the grenades consists of a 95:5 mixture of red phosphorus and styrene-butadiene rubber (butyl rubber) in the presence of methylene chloride, which is later removed by low temperature drying (Lundy and Eaton 1994).
Can low oil cause white smoke?
No, white smoke is not indicative of burning oil. If valve seals go faulty or if oil leaks from the piston this will result in oil seeping into the combustion chamber. When oil seeps into the combustion chamber it will mix with fuel resulting in a blue-colored smoke from your exhaust.
Is it legal to own a military smoke grenade?
It’s not illegal to buy them, it’s not illegal to use them, provided you’re over 18, you can pull that pin. Just use them on your own land or seek permission. If you cause panic or a disturbance then you most certainly will be breaking a law, so you must use discretion.
