There is no path of electrons around the nucleus. There are however things called orbitals where you are likely to find electrons.
Scientists change the independent variable; The dependent variable is the one that reacts to the independent variable.
Answer:
The name of the phase change is;
Sublimation.
Explanation:
CO₂(s) + energy ⇒ CO₂(g)
Sublimation is the transition of a substance from its solid state to the gaseous state without first turning to a liquid due the high rate of absorption of of thermal energy of the substance such that the substance does not melt first.
As such sublimation is the endothermic process taking place at a temperature and pressure lower than the triple point of the substance in the substance's phase diagram. The triple point is the lowest temperature and pressure at which a substance can exist as a liquid.
