Question

How many degrees of freedom does each of the following systems have? (Answer as a number, i.e., 1, 2, 3, etc.)

1. Liquid water in equilibrium with its vapor?

2. Liquid water in equilibrium with a mixture of water vapor and nitrogen?

3. A liquid solution of alcohol in water in equilibrium with its vapor?

Answer 1

Step-by-step explanation:

Hello, since the Gibbs' phase rule states the following equation:

`F=C-P+2`

Whereas C is the number of components and P the present phases, you answers are:

1. F=1-2+2=1.

2. F=2-2+2=2.

3. F=2-2+2=2.

Best regards.
