Answer 2

Answer:

Triple point has zero degree of freedom. Therefore the triple point of one component system is invariant.

Explanation:

• Triple point is point where all the three phases of component are in equilibrium.
• According to the phase rule, the degree of freedom of one component system will be:        

                  $F=C-P+2$

        where  F is the degree of freedom

                    P is  phases in equilibrium

                    C is component in the system

• Now for triple point, when there are three phases in equilibrium. Therefore the value of P=3 and value of C=1.

      Therefore,

                $F=C-P+2 \\ F=1 - 3+2 \\ F=3 - 3 \\ F=0$

Therefore, the triple point for one component system such as water is invariant.
