What is the relation between vapour pressure and tendency to evaporate?
Answer and explanation
Correct answer: Direct relation
At a fixed temperature, vapour pressure reflects the escaping tendency of molecules from a liquid. If molecules evaporate more readily, more vapour accumulates before equilibrium is established, producing a higher vapour pressure. Thus the relationship is direct. The exact pressure still depends on temperature and the nature of the liquid.
