Is it possible to have only liquid in a closed container?
I recently read an answer by Aman Rusia for this question: Is a liquid in a container always in equilibrium with its vapour?
In it, they say that
You can't have a container filled with only ...

Freezing point of solution
It's stated in my textbook that at the freezing point, the vapour pressure of the solid phase equals the vapour pressure of the liquid phase. In a mixture, since the vapour pressure of the solution is ...

Is liquid water in equilibrium with water vapor at room temperature?
This question was inspired by Why does liquid water form when we exhale on a mirror?.
This question is different from Why does water evaporate at room temperature? because it asks about whether an ...

Water vapour pressure in oxygen gas bubble
Suppose we have a source of O$_2$ bubble formation in water at specific nucleation sites, how can we estimate the water vapour pressure inside the O$_2$ bubbles?
I know that:
(1): $p_\mathrm{O_2}+...

How to without calculations understand the liquid-liquid extraction efficiency?
I'm asking myself this question for a very long time and I haven't found a simple an good explanation yet for the fact that it's better (if you want to clean them) to wash your hands two times with ...

Why are temperature and pressure represented as the number 2 in Gibbs' Phase Rule?
In our class we are learning about Gibbs' Phase Rule; $F=C-P+2$, in which $F$ stands for degree of freedom, $C$ for number of components, and $P$ for number of phases in the system. Our professor told ...

What causes both components of a binary gas mix to condensate at the same time for a given composition
Okay, so recently I encountered the temperature - mole fraction diagrams for binary vapour-liquid equilibrium. For now, I only consider two-component systems where the components are very similar and ...

If melting points and freezing points are the same, what state is pure equilibrium?
If melting points and freezing points are the same, what state is pure equilibrium?
I understand melting points and freezing points are the same; adding or removing temperature of melting points for ...

Effect of pressure on the freezing temperature of water
A few lines are written in a book by B.H. Mahan regarding the change in freezing point of water on changing the pressure.
The vapor pressure of water at triple point of water is 4.579 mm. What ...

Does aqueous component contribute to the equilibrium constant?
Consider an equilibrium reaction with an aqueous solution $\ce{A(aq)}$ in equilibrium phase with gas:
$$\ce{A(aq) + B(g) <=>[$K_\mathrm{eq}$] C(g)}$$
Would the equilibrium constant have aqueous ...

Equilibrium involving water and solid component
$$\ce{A + B <=> C(s) + H2O(l)}$$
Why when $\ce{H2O}$ is liquid and $\ce{C}$ is solid, the equilibrium constant of the reaction is
$$K_\mathrm{eq} = \frac{1}{[\ce{A}][\ce{B}]} \quad ?$$

Proof of Dynamic Nature of Equilibrium
Here is how my textbook proves that dissolution of solid in liquid is dynamic in nature. It considers the example of a saturated solution of sugar. It says that,
Though the solution is in ...
