stable amounts of glucose iodine does this.
Hydrogen
It's a liquid but in the form of a very fine spray or mist. A fine misting water sprayer makes exactly the same kind of cloud. Water in its gas form is called steam and is invisible and must be at a temperature of over 100 Celsius - it cools to below that rapidly after (for example) it leaves the spout of a kettle and appears as a cloud 2-3cm beyond the end of the spout, at which point it is water again, not a gas, and is visible.
The mixture of equimolecular amounts of hydrogen and carbon monoxide is called water gas.
neither. the water needs to be boiling to create gas. Hot water will not create gas and cold water will not create gas. Yes, hot water will create gas more quickly than cold if boiled tho
