In the gaseous state, it might seems that it is the spinning negative temperature particles which present a positive gravitational force directed along their axes of rotation that counter earth's gravity and enables the material to break free and fly off.
In this case, we would have assigned the signs of temperature particles wrong.
It is the positive temperature particles that attract a negative temperature particle to spin around them and so manifest a gravitational force that counteracts gravity. This turns the material into a gas. Since, temperature particles are discrete entity, it is possible that the material breaks away without passing through the liquid state on the acquisition of an negative temperature particle, Sublime.
A negative temperature particle spinning by itself, may generate enough gravitational force along its axis of spin to counter gravity. When this happens, at low temperature, the material also attains a gaseous state. The material evaporates away on the exposed surface. A sort of cold corrosion.
A fluid boiling, occurs at the fluid/container contact surface, and evaporation occurs on the surface of the fluid. Both occur where it is possible for positive temperature particles to attract negative temperature particles.
All these introduce a new factor in the transition to the gaseous state, the need to acquire negative temperature particles. These particles in orbit around positive temperature particles generates a positive gravitational field that counters earth's gravity.
