I get kind of nervous when a geologist starts saying it's possible!

Do not let your kids eat the hail or drink the rainwater. It is likely to contain some benzene and cyclohexane. Can it rain oily compounds? The short answer is it certainly can. It is also not complex to work out which chemical compounds will be coming down in our rainwater. It is those with a similar boiling point and freezing point to water. It is those that are not too heavy, that are similar to that of air at 1.2 kg per cubic meter. They should be able to rise easily to upper atmospheric levels.

Let us start with water. On earth at everyday working temperatures matter has 3 phases. They are solid, liquid and gas. We know these phases by other names called ice, water and steam.

Water is ICE or a SOLID at 32 degrees F or below that temperature. It turns to WATER or a LIQUID at temperatures slightly above 32 degrees C. It starts evaporating as soon as it is liquid and starts changing to steam or vapor until at our atmospheric pressures, at sea level, it is all STEAM or WATER VAPOR or GAS at 212 degrees F.

In the case of benzene and cyclohexane, these chemical compounds found in oil, change from a solid (ice) at 42 and 44 degrees F, and start evaporating rapidly until at 176 and 177 degrees F they are all vapor or gas.

Good thing the water isn't 176F degrees huh? Damn read the very article you posted from before jumping to mad outlandish delusions.

How about you re-read it. It starts evaporating when starting to turn to liquid (42-44F)... and continues evaporating until 177F when it's ALL vapor/gas. Just as water can start evaporating when it reaches 32+F and continues until it's all vapor/gas at 212F.

The water doesn't need to be 176F... it only needs to be above 44F for evaporation to begin (obviously the higher the temp - the more the evaporation).

Once air born can it attach itself to dust or water particles?

Dropped by air some of it will have evaporated before it even hits the water.
