¿Qué sucede cuando un líquido se congela y se evapora al mismo tiempo? Las sustancias solo pueden ser líquidas en presencia de algún gas que aplican la presión suficiente para mantenerse en ese estado. Si esa presión no existe o es mínima, la sustancia "saltará" de estado sólido directo al gaseoso a medida que su temperatura aumenta. Si esto sucede en un espacio cerrado, el gas (vapor) producido aumentará creando presión a medida que sucede, de tal forma que un estado líquido, que antes no era posible, ahora sí es posible.
