Pure substance at sublimation line exist as a mixture of liquid and

False

Explanation:

A graphical representation of transition of substance's physical state under various temperature and pressure conditions is known as phase diagram.

A typical phase diagram usually consists of:

(A) Fusion curve - The curve that represents that the solid and the liquid state exists in the equilibrium with each other is called fusion curve.

(B) Vaporization curve - The curve that represents that the liquid and the gaseous state exists in the equilibrium with each other is called fusion curve.

(C) Sublimation curve - The curve that represents that the solid and the gaseous state exists in the equilibrium with each other is called fusion curve.

(D) Triple point - This is a point in the phase diagram in which all the three state exists in equilibrium.

Thus, for a pure substance, sublimation line exist as a mixture of solid and gas. The statement is false.

answer:

explanation:

assault rifle is a rapid-fire, magazine-fed rifle designed for military use. it is a shoulder-fired weapon that allows the shooter to select between semi-automatic (requiring you pull the trigger for each shot), fully automatic (hold the trigger and the gun continuously fires) or three-shot-burst modes.
