Hello.

 

Do you know of any inorganic compound in powder form that becomes gas when triggered by an 'stimulus' like light, microwaves, heat...

 

Like every particle of the powder release or turn to gas ? I want to make bubbles, megazillions of them... :rolleyes:

 

How is styrofoam made? Is it by mixing two chemicals or by external stimulus ?

styrofoam is made by mixing polystyrene and a solvent in an extruder (the mixture is at high pressure/temperature inside the extruder).

 

When it leaves the extruder, the pressure becomes atmospheric, and the solvent which is inside the polystyrene expands a lot, and the polystyrene becomes the foam (with the solvent gas in the air-pockets).

 

then you have to leave it for a while so that air can replace the solvent in the air-pockets in the foam.

 

But styrofoam is organic... not inorganic.
