Question

The triple point in a phase diagram is
(a)
Univariant
(b)
Non-variant
(c)
Bivariant
(d)
Trivariant​

Answer 1

Answer:

answer is (b) Non-variant

Explanation:

plz follow me

Answer 2

Answer:

(b) non-variant

Explanation:

acc.to gibbs phase rule F=C-P+2

,at triple point 3phases co-exist

hence,F=1-3+2=0

when degrees of freedom is zero then system is said to ne non-variant or invariant.
