The conditions at which the solid, liquid, and gaseous phases of a substance can exist in equilibrium with one another is called
a. boiling point.
b. freezing point.
c. sublimation point.
d. triple point.

The answer is:  [D]:  triple point .

Answer choice [A]: boiling point; refers to the temperature at which the equilibrium vapor pressure of the liquid equals the atmospheric pressure.

Answer choice [B]: freezing point; refers to the temperature at which the solid and liquid are at equilibrium at one atm (1 ATM pressure).

Answer choice [C]: sublimation point; refers to a change directly from the solid to the gaseous state without becoming liquid.

They are all decomposition reactions.
