Give one example of each of the following equilibria:
Liquid-Gas Equilibria
$$\text { When distilled water is heated at a given } \\$$
$$\text { temperature, vapours form. After a } \\$$
$$\text { particular time, level of water becomes } \\$$
$$\text { constant, this occurs when rare of } \\$$
$$\text { evaporation = rare of condensation and } \\$$
$$\text { no more conversion occur, hence an } \\$$
$$\text { equilibrium is established } \quad \mathrm{H}_{2} \mathrm{O}(\mathrm{l}) \rightleftharpoons \mathrm{H}_{2} \mathrm{O}(\mathrm{g})$$
