What is the nature of equilibrium between the liquid surface and its vapours in a closed vessel ?

What is the nature of physical equilibrium ?

What is the nature of chemical equilibrium ?

Can equilibrium be achieved between water and its vapours in an open vessel ? Explain yours answer and say what happens eventuallly.

A liquid boils when its vapour pressure equals

A liquid is kept in a closed vessel. If a glass plate (negligible mass) with a small hole is kept of top the liquid surface, then the vapour pressure of the liquid in the vessel is :

A vessel has two compartments connected at the top. In one compartment (B), radioactive methyl ioddide (overset(**)(C)H_(3)I) is placed while in other compartment (A). Normal methly iodide "("CH_(3)I")" is placed. Will the vapours over (A) and (B) become radioactive ? Will the radioactivity spread to the liquid in compartment A? Discuss in terms of dynamic nature of the equilibrium between the vapours and the liquid.
