It is icing over and is either low of refrigerant or the coils are dirty.
When an exhaust pipe is cool, the exhaust will start to allow water vapor to condense. If the exhaust is white you're seeing a vapor cloud; it's normal and unavoidable. Once the engine and exhaust are warm, the vapor cloud should stop.
Does the engine have spark? White fumes could possibly be fuel vapor.
Mercury vapor streetlights, used since the 1940s, glow a greenish white. Sodium vapor streetlights, which have gradually replaced most of the MV streetlights in the US, glow orange. Another two, metal halide and LED, glow completely white.
White frozen water vapor is called snow. It forms when water vapor in the atmosphere freezes into ice crystals, which then fall to the ground as snowflakes.
could it be white vapor? If so its probably head gasket.
No. True steam is transparent. The white puffs of vapor you see coming from a tea kettle are water vapor, not steam.
White, water vapor. Gray/black unburned gasoline. Blueish, burning oil.
yes most gasoline/ petrol burning cars will have more water vapor in a cold start situation
Condensation (water vapor).
The gas that forms dense white fumes with ammonia vapor is hydrochloric acid (HCl). When HCl gas comes into contact with ammonia vapor, it forms solid ammonium chloride (NH4Cl) particles, which appear as a dense white smoke or fumes.
Sodium vapor streetlights emit a warm yellow-orange light, while mercury vapor streetlights emit a bluish-white light. Sodium vapor lights are more energy-efficient and have a longer lifespan compared to mercury vapor lights. Additionally, sodium vapor lights are better at preserving night vision and reducing light pollution.
Atmospheric water vapor frozen into ice crystals and falling in light white flakes or lying on the ground as a white layer.
