On heating a closed vessel containing liquid and vapour in equilibrium, which statement is correct?
Fraction of molecules in vapour phase increases
On heating a closed vessel at liquid-vapour equilibrium, more liquid vaporizes as temperature rises, so the fraction of molecules in the vapour phase increases, while the total number of vapour molecules does not remain constant.
