Question

The number of degree of freedom at triple point for the water system is

Answer 1

Answer:

For a pure substance, number of components (N) is 1, number of phases at triple point ( ) is 3 (solid, liquid, vapor). So the number of degrees of freedom is, Thus, the number of degrees of freedom for the substance is 0.

So here is your answer dear

Answer 2

Answer:

The number of degree of freedom at triple point for the water system is zero (0).

Explanation:

Triple point: The temperature and pressure at which the solid, liquid, and vapor phase of a pure substance coexists in equilibrium are called the triple point.

As a pressure below the triple point line, the substance cannot exist in the liquid phase, and the substance when heated transforms from solid to vapor by absorbing the latent heat of sublimation from the

Gibb's phase rule is given by,

P+F=C+2

where, P = No of phase, F = Degree of freedom, C= No of components

Now,

Pure substance (C) = 1

At triple point, (P) = 3

3 + F = 1 + 2

F = 0

Therefore, the degree of freedom at triple point for water is zero.
