Answer:
Under the equilibrium condition
Explanation:
according to the phase rule given by Willard Gibbs, under the condition where the equilibrium between the number of phases is not affected by the gravity, electricity magnetic force or by surface action and the system is under constant temperature, pressure and concentration then the degrees of freedom(F) is proportional to the concerntration (C) and the Phases(P) at equilibrium condition.
the expression is given as : F= C-P+2

Valence electrons are the electrons in the outermost shell and can be used to form bonds.
Answer:
/D/ either absorbs or releases energy
Explanation:
During a phase change energy is either absorbed or released.
A phase change is a reversible process which occurs when a substance changes is its state from one form to another.
Phase changes are used to delineate physical changes.
- A phase diagram provides a graphic representation of the change.
- The diagram can be 2 dimensional or 3 dimensional.
