Solid+To+Gas

TaylorSolid To Gas = =  The question is How does a solid change from a solid to a gas. A solid can go from a solid to a gas by going through "phases". That would be starting off as a solid then changing to a liquid then changing to a gas. But there is a way it can change directly from a solid to a gas. This is called "sublimation". It is a endothermic phase transition that occurs at temperatures and pressures below the the triple point. This can occur if the atmospheric pressure exerted on the substance is too low to stop the molecules from escaping from solid state. A good example of this would be frozen CO2     or "Dry Ice" witch is at -109.3 ° F                Compression Explaining The Triple Point.
